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.
