buildman: Allow ignoring warnings in the return code
Sometimes we don't want buildman to return failure if it seems warnings.
Add a -W option to support this. If buildman detects warnings (and no
errors) it will return an exit code of 0 (success).
Note that the definition of 'warnings' includes the migration warnings
produced by U-Boot, such as:
===================== WARNING ======================
This board does not use CONFIG_DM_MMC. Please update
...
====================================================
