Measured on a PS5 (firmware 13.60): sceSysmoduleIsLoaded,
sceSysmoduleLoadModule and sceSysmoduleUnloadModule with id 0, and the
Internal and InternalWithArg calls with id 0 or 0x80000000, return
0x805A1000 and leave the WithArg result untouched. They threw.

Drop the retry on <name>.prx after libs/<name>.prx fails. The test now
runs from its own directory holding libs/libSceFiber.prx, copied from
the libSceFiber output, so the single path resolves in the test too.

Return a host module handle for a loaded sysmodule id so callers can
sceKernelDlsym after sceSysmoduleLoadModule. Unknown or null inputs
throw like neighbouring internal load paths; unloaded ids return
0x805A1001. Unblocks Prospero Win past NID D8cuU4d72xM at load.

It carried its own copy of the /proc/self/maps line scan and is called on the same Unity stack walks as sceKernelGetModuleInfoForUnwind. It now uses the shared HostMapping lookup.
sceSysmoduleIsLoaded returned 0x80A90002 and the unload calls 0x80A90003
for a module that is not loaded. Neither value exists in the SDK: the
sysmodule facility is 0x5A and the error is 0x805A1001, which titles
compare against (GTA V PPSA04263: cmp eax,0x805a1001 after IsLoaded) to
decide whether to load and initialise the module themselves. Return that
value from all three places and cover it in guest_sysmodule.

Two exports were missing. System modules are linked statically, so load and unload are
reference counts over the known module table, exactly like the existing
sceSysmoduleLoadModuleInternalWithArg and sceSysmoduleUnloadModule:
- sceSysmoduleLoadModuleInternal(uint32_t) -> increments the module's load count, returns 0
- sceSysmoduleUnloadModuleInternal(uint32_t) -> decrements it, or 0x80A90003 when the module
was not loaded
Unknown or zero ids throw, like the sibling internal loader. Adds a CMakeLists.txt so the
library can carry its guest test. Signatures follow the public OpenOrbis SDK headers.
New test core/libs/tests/GuestSysmodule.cpp loads a module twice, unloads it twice and checks
the not-loaded error on a third unload; it fails without the change (the symbols are
undefined) and passes with it.
sceSysmoduleLoadModule and sceSysmoduleIsLoaded already accept ids the
project does not know and log them; unloading such an id threw, so a title
that loads and later unloads an unknown module aborted at the unload.

libSceSysmodule/Export.cpp parsed /proc/self/maps device major/minor
numbers into signed int with a %x format, which is undefined behaviour
per the C standard even though it happened to work on this target;
switched to unsigned int to match the format specifier.
NidPatcherUtils.hpp's StripNidPostfix built a truncated copy with
substr(0, n) where the prefix is already the string itself; resize(n)
does the same truncation without the extra allocation and copy.
