Subject: [PATCH] skip the emulation check in chrootless mode

Whenever the selected architecture differs from the native architecture
of the system that runs mmdebstrap, mmdebstrap checks whether it can run
the selected architecture. In the majority of cases, this is good and
helps avoid difficult to diagnose issues. However when running in
chrootless mode, we don't actually want to run any binaries from the
target system. For that reason, the emulation check should be skipped in
chrootless mode.
