Subject: [PATCH] Include sys/sysmacros.h in testlib.h

In recent Linux systems, major() and minor() are defined in
sys/sysmacros.h and sys/types.h no longer includes sys/sysmacros.h.  So,
we need to include sys/sysmacros.h in testlib.h.

Also adds a check for the existence of sys/sysmacros.h in configure.ac.

Include sys/sysmacros.h in testlib.h
