Subject: [PATCH] mraa: Use posix basename
Musl has removed the declaration from string.h [1] which exposes the
problem especially with clang-17+ compiler where implicit function
declaration is flagged as error. Use posix basename and make a copy of
string to operate on to emulate GNU basename behaviour.
