That seems better even in the xf86drmMode.c, <sys/sysctl.h> is required
for sysctlbyname() called from drmCheckModesettingSupported() with
FeeBSD build macro.

Unfortunately, I am not the meson build expert so if there is someone to
fix, then I am okay. Anyway, I will try to fix with HAVE_SYS_SYSCTL_H.
