Bazel: Rename rules to be compatible with gerrit

Gitiles is used as repository viewer in gerrit code review. For this
gitiles-servlet is consumed in gerrit-gitiles-plugin. For development
purpose we would like to short cut the consumption of gitiles-servlet
directly from gitiles repository. To make it possible, rename targets
to match the names in gerrit.
