Subject: [PATCH 1/1] xfsdump: Mimic GNU basename() API for non-glibc library
 e.g. musl

musl only provides POSIX version of basename and it has also removed
providing it via string.h header [1] which now results in compile errors
with newer compilers e.g. clang-18

[1] https://git.musl-libc.org/cgit/musl/commit/?id=725e17ed6dff4d0cd22487bb64470881e86a92e7
