David 4dd97f7dbe feat(libkernel): implement chflags through the guest path resolver
PS5MC (PPSA99420, Kodi 22) imports chflags (ixrw0h2tWuI) from
libkernel.prx, one reference. Predicted stop once the imports ahead of
it (pthread_getthreadid_np, sendfile, wcstok, pause, setrlimit and the
termios calls) are covered (not a run):

  FAIL: unresolved ELF import ixrw0h2tWuI from libkernel.prx

The NID is computed with tools/nid_names.py and matches aerolib.

Follows FreeBSD 11.4 (8c639945a44588f6cfdddfb057bb5aad88735da0)
sys/kern/vfs_syscalls.c kern_chflagsat and setfflags, and
sys/ufs/ufs/ufs_vnops.c ufs_setattr, for a root caller: the lookup
through the guest resolver gives EFAULT, ENOENT and ENOTDIR (also for a
file reached through a trailing slash or used as a directory), a bit
outside the 17 UFS flags of sys/sys/stat.h (VNOVAL included) gives
EOPNOTSUPP, and SF_SNAPSHOT gives EPERM, since the snapshot flag cannot
be toggled. No host keeps BSD file flags and stat reports st_flags 0,
so flags 0 succeed without touching the file and any other flag throws
with the flags named. UF_READONLY and the other Windows-attribute flags
are not mapped to FILE_ATTRIBUTE_READONLY and its siblings: UFS stores
them without enforcing them, and on Windows the read-only attribute is
already the owner write bit of chmod.
