Maven artifact names on Google bucket replacing SNAPSHOT suffix with
timestamp. 731967591e changed this by
preserving the SNAPSHOT suffix. This broke fetching of gwtorm and
gwtjsonrpc and was reverted by 731967591e.
This change fixes this for both worlds: stripping it for GERRIT and
GERRIT_API Maven repositories but preserving it for the rest.
Test plan:
maven_jar() is working as expected for the both worlds:
* gwtorm:gwtorm:1.10-SNAPSHOT-20140310.015132-1 (repo = GERRIT)
* org.eclipse.jgit:org.eclipse.jgit:3.4.0-SNAPSHOT (repo = MAVEN_LOCAL)
