meson: fix sys/mkdev.h detection on Solaris

Browse source 
On Solaris, sys/sysmacros.h has long-deprecated copies of major() & minor()
but not makedev().
sys/mkdev.h has all three and is the preferred choice.

Let's make sure we check for all 3 major(), minor() and makedev().

Fixes build failure with error:
../xf86drm.c: In function ‘drmOpenMinor’:
../xf86drm.c:454:30: error: implicit declaration of function ‘makedev’ [-Werror=implicit-function-declaration]
  454 |         return drmOpenDevice(makedev(DRM_MAJOR, minor), minor, type);
      |                              ^~~~~~~
