vfio: include libgen.h (for musl compatibility)
Starting GCC14 'implicit-function-declaration' are treated as errors by
default. When building kvmtool with musl libc, the following error
occurs due to missing declaration of 'basename':
vfio/core.c:537:22: error: implicit declaration of function ‘basename’ [-Wimplicit-function-declaration]
537 | group_name = basename(group_path);
| ^~~~~~~~
vfio/core.c:537:22: warning: nested extern declaration of ‘basename’ [-Wnested-externs]
vfio/core.c:537:20: error: assignment to ‘char *’ from ‘int’ makes pointer from integer without a cast [-Wint-conversion]
537 | group_name = basename(group_path);
| ^
This patch fixes the issue by including the appropriate header, ensuring
compatibility with musl and GCC14.
