So in glibc-2.23 sys/sysmacros.h is no longer included from sys/types.h
and we don't build because of the usage of major/minor/makedev macros.
Autoconf already has AC_HEADER_MAJOR macro that check where exactly
these functions/macros are defined, so let's use that.

v2:
 - Don't include the file unconditionally, but rather use
   AC_HEADER_MAJOR that exists for exactly this purpose.

I've just found out about the breakage by upgrading glibc and almost
blamed you as I've misunderstood this patch.

This fixes the build for me and the usage of AC_HEADER_MAJOR looks on
the spot to me.

ACK

Thanks but you're not the only one, so let's wait for the consensus to
be reached.
