wiphy: Remove basename() use

Browse Source 
basename use is considered harmful.  There are two versions of
basename (see man 3 basename for details).  The more intuitive version,
which is currently being used inside wiphy.c, is not supported by musl
libc implementation.  Use of the libgen version is not preferred, so
drop use of basename entirely.  Since wiphy.c is the only call site of
basename() inside iwd, open code the required logic.
