Make OpenJDK build work with repo .git directories

Repo creates .git directories with a dangling .git/shallow symlink,
which causes a make error:
make[1]: *** No rule to make target `/home/build/out/hotspot/.git/shallow', needed by `/home/build/out/build/linux-x86_64-normal-server-release/hotspot/_hotspot.timestamp'.  Stop.

Prune .git directories along with .hg directories.
