By default, qemu user's home dir points to '/' which shouldn't be used
at all. We therefore pass the HOME variable from the current variable
iff not running as SUID, which means that for systemd we never set it.
This patch makes sure, that for system QEMU this is always set to
libDir/<driver>, session mode is left untouched.

For session mode, only XDG_CACHE_HOME is set, because we want to remain
integrating with services in user session, but for system mode, this
would have become reading/writing to '/' which carries the obvious issue
with permissions (also, '/' is the wrong location in 99.9% cases anyway).

In order to test SEV we need real QEMU capabilities. Ideally, this would
be tested with -latest capabilities, however, our capabilities are
currently tied to Intel HW, even the 2.12.0 containing SEV were edited by
hand, so we can only use that one for now, as splitting the capabilities
according to the vendor is a refactor for another day. The need for real
capabilities comes from the extended SEV platform data (PDH, cbitpos,
etc.) we'll need to cache/parse.
