build: added Debian Lenny's copy of pkg.m4

New versions of pkg-config's autoconf m4 files set the variables
PKG_CONFIG_PATH and PKG_CONFIG_LIBDIR as precious... which means that
configure caches the original values and our subdir overrides are lost.
This copy of pkg.m4 overrides whatever is on the system, and avoids
such preciousness.
