[PATCH libdrm 2/2] meson.build: Fix meson script on FreeBSD

[Niclas Zeising]

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.

FreeBSD doesn't normally ship bash, try regular sh instead if we can't
find bash.
