ceilometer: Fix libvirt-bin group name for armband.

ceilometer: Fix libvirt-bin group name for armband.

Upstream mirrors use a custom version of libvirt, ported from
Debian, while keeping the Ubuntu ceilometer package, leading to a
libvirt group name mismatch between the two.

Fuel-library hardcodes a deb-version test for libvirt-bin, which
enforces the use of "libvirt" instead of "libvirtd" for 1.2.9 or
newer libvirt-bin [1].

Armband brings its own 1.3.2 libvirt-bin package, which respects
Ubuntu standard group naming ("libvirtd"), but since 1.3.2 > 1.2.9,
the old group name ("libvirt") is still used.

This patch extends the version checking introduced in [1]:
 - libvirt-bin 1.3.2 or newer will use "libvirtd" naming;
 - libvirt-bin 1.2.9 ... <1.3.2 will use "libvirt".
