Subject: fix building w/newer C libraries

Linux C libraries are moving away from implicitly including the header
sys/sysmacros.h via sys/types.h.  We would like to do this for glibc
now, but others (musl/etc...) have been doing it already.  This means
any code using major/minor/makedevs functions will fail to build when
they don't include that header.

Leverage the AC_HEADER_MAJOR macro that configure is already using to
pull in the right header.
