[U-Boot] [PATCH v3 18/18] buildman: Ignore conflicting tags

[Simon Glass]

Tags like Series-version are normally expected to appear once, and with a
unique value. But buildman doesn't actually look at these tags. So ignore
conflicts.

This allows bulidman to build a branch containing multiple patman series.
