[OSSTEST PATCH 21/27] make-flight: Contemplate varying architecture for Debian HVM

[Ian Jackson <ian.jackson@eu.citrix.com>]

In the Debian hvm tests, ask branch_debianhvm_arch for the
architecture to use.  This currently prints only amd64.

While we are here, provide some comments about the (somewhat
confusing) argument conventions of do_hvm_debian_test_one.

No functional change yet.
