m4: Add PKG_PREREQ version checking macro
While PKG_PROG_PKG_CONFIG checks the version of pkg-config available at
build time, it doesn't check the version of the pkg-config macros being
used. PKG_PREREQ (like AC_PREREQ or LT_PREREQ) can be used to check the
version of the macros in use when configure is being generated by the
developer.
