[U-Boot] [PATCH 1/2] buildman: Allow conflicting tags to avoid spurious errors

[Simon Glass]

Conflicting tags can prevent buildman from building two series which exist
one after the other in a branch. There is no reason not to allow this sort
of workflow with buildman, so ignore conflicting tags in buildman.
