[PATCH libdrm v2 4/4] meson.build: Fix meson script on FreeBSD

[Emil Velikov]

From: Niclas Zeising <zeising at daemonic.se>

FreeBSD requires sys/types.h for sys/sysctl.h, add it as part of the
includes when checking for headers.
Instead of splitting out the check for sys/sysctl.h from the other
header checks, just add sys/types.h to all header checks.

v2 [Emil]
 - add inline comment
 - drop bash/sh hunk
