futility/updater: Ignore preserve_me quirks for non-host programmers.

The preserve_me quirk allows avoiding modifying the ME region while it
may be running. Its apply function attempts to skip itself when not
flashing the OS-bundled firmware by checking for whether an archive is
set, but this doesn't work since in the absence of an actual archive
file, a filesystem archive implementation is used instead.

While flashing over a non-host programmer the ME is not running and
therefore it is safe to update the ME region.

Add unit test cases for the preserve_me quirk applying successfully when
using the default host programmer and being skipped when using another
programmer.

TEST=futility update -p dummy... with preserve_me quirk skips the quirk;
     chromeos-firmwareupdate with a preserve_me quirk applies the quirk
