Andrea Bolognani e64f2fab92 m4/virt-arg: Rename LIBVIRT_ARG_WITH* macros
LIBVIRT_ARG_WITH_ALT is more generic than LIBVIRT_ARG_WITH, which
is tailored at switching features on and off.

Rename the macros according to their intended purpose, and add
some documentation to help developers pick between the two.
