Buildroot commit [1] "kvmtool: bump to f77d646ba0" removed the
definition of KVMTOOL_EXTRA_LDFLAGS but forgot to remove its usage
in KVMTOOL_MAKE_OPTS.
This commit removes it since it is no longer needed.

-Subject: vfio: include libgen.h (for musl compatibility)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-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.
