[oe] [PATCH] metadata_scm.bbclass: get the metadata revision for current HEAD

[Khem Raj]

Currently we report wrong revision when we build from branches not based
on master because we only fetch the HEAD value which is remote master
This patch makes it to report the HEAD of whatever branch one has
checked out.
