Add an option to allow the admin to requet a higher minimum SSF
for connections than the built-in default.
The current default is 56 (single DES equivalent, to support

The presence of this capability depends on QEMU being compiled
with spice that has the SPICE_ADDR_FLAG_UNIX_ONLY constant.
It was added by spice commit 5365caeaae released in spice v0.12.6,
which is older than the spice version on our supported architectures.
