From: Adrian Freihofer <adrian.freihofer@siemens.com>

Tests can not query variable flags with get_bb_vars. They either need
another bitbake invocation per flag or the metadata needs to copy the
flags into variable values just to make them visible to the tests.

Add get_bb_vars_flags, a more generic variant of get_bb_vars which reads
variables as well as variable flags with a single tinfoil session.
get_bb_vars is implemented on top of it, its return values do not
change.
