Subject: [PATCH] drm/xe: add missing include <libgen.h>

basename() got implicitly included on glibc but not on other libc's like
musl libc and therefore fails to build:

/home/achill/git/user-aports/experimental/linux-mainline/src/linux-6.17-rc3/drivers/gpu/drm/xe/xe_gen_wa_oob.c: In function 'fn_to_prefix':
/home/achill/git/user-aports/experimental/linux-mainline/src/linux-6.17-rc3/drivers/gpu/drm/xe/xe_gen_wa_oob.c:130:14: error: implicit declaration of function 'basename'; did you mean 'rename'? [-Wimplicit-function-declaration]
  130 |         fn = basename(fn);
      |              ^~~~~~~~
      |              rename

  130 |         fn = basename(fn);
