Subject: metadata_scm.bbclass: simplify base_detect_revision()

The previous code looks strange because of historical reason, simply return
base_get_metadata_git_revision/branch() is enough, the later functions has
handled everything like '<unknown>' and strip().

(From OE-Core rev: 8a6e70960e021e10a1d02e20e0519fdbdeac8616)
