Add missing includes

[sertonix]

Missing includes are considered an error since GCC 14

Looking good.

@sertonix Out of curiosity: how did need for libgen.h come up? Did you get compilation time warnings?

... the idea has sort of been to explicitly avoid libgen.h by using GNU basename() via

#define _GNU_SOURCE
#include <string.h>

[sertonix]

These patches came from alpine linux which uses musl libc. And musl libc follows the posix spec which only requires basename(3) in libgen.h.

... which uses musl libc. And musl libc follows the posix spec ...

NB This would have been better context info for the PR than gnu version something.

Anyway, posix basename() behavior differs from gnu basename(). MCE codebase expects gnu basename(). Which makes blindly taking posix basename in use = Incorrect fix for the musl problem.

Please check / review / test: #31

Yes, that seems to work too. It looks like musl only does modifications to path that didn't change the behavior.
