nodeinfo: remove FreeBSD specific code for getting memory

The GNULIB physmem module already provides support for
the FreeBSD platform, so there's no reason to re-implement
FreeBSD portability code in libvirt. If there are bugs in
the GNULIB code, we should fix GNULIB rather than workaround
it in libvirt.
