bootstd: Allow EFI bootmgr to support an invalid bootflow

Browse source 
For most testing we don't want this bootmeth to actually do anything. For
the one test where we do, add a test hook to obtain the correct behaviour.
This will allow us to bind the device always, rather than just doing it
for this test.
