unittests: Test env2mfile's dpkg_architecture_to_machine_info

Browse Source 
This test parses several possible outputs of dpkg-architecture and
asserts that they produce the expected MachineInfo.

To avoid depending on suitable cross-tools being installed, use
unittest.mock to override locate_path with a version that pretends that
all of the tools we're interested in are in /usr/bin.
Similarly, use mock environment variables to exercise what happens
when we have those set.

The test data used here exercises most variations:

* big- and little-endianness
* GNU CPU (x86_64) differing from dpkg CPU (amd64)
* Linux, kFreeBSD and Hurd
* special-cased architectures: x86, arm, mips64el, ppc64el

expected_compilers() intentionally doesn't assume that every compiler
is gcc (even though they all are, right now), because #13721 proposes
adding valac which does not take a gcc suffix.
