mg-debian-installer-update: Honour OSSTEST_SPECIALKERNELDEB_<suite>_<arch>

This variable can be set to the absolute pathname of a kernel .deb to
use.  It will be used only for hosts for which the corresponding
hostflag "need-kernel-deb-<suite>-special" is set.

There is not currently any facility for more than one special kernel
for each architecture.

As with backports kernels, the normal (Debian-supplied) kernel is
available too, and is used for hosts without any special hostflag.
