app-emulation/xen: provide a sub-slot

Technically when switching between minor versions (e.g. 4.5 -> 4.6) you
need to rebuild anything that has linked against the Xen libraries due
to no promise of ABI stability between those versions. So expose a
sub-slot so packages can be rebuilt appropriately.
