[PATCH kvmtool v2 1/2] Switch to POSIX version of basename()

[J. Neuschäfer <j.neuschaefer@xxxxxxx>]

There are two versions of the basename function: The POSIX version is
defined in <libgen.h>, and glibc additionally provides a GNU-specific
version in <string.h>. musl-libc only provides the POSIX version,
resulting in a compilation failure:

vfio/core.c:538:22: error: implicit declaration of function 'basename' [-Werror=implicit-function-declaration]
  538 |         group_name = basename(group_path);
      |                      ^~~~~~~~
