With --detect-labels enabled, git-p4 will try to create tags
using git fast-import by writing a "tag" clause to the
fast-import stream.
If the commit that the tag references has not yet actually
been processed by fast-import, then the tag can't be created
and git-p4 fails to import the P4 label.
Teach git-p4 to use fast-import "marks" when creating tags
which reference commits created during the current run of the
program.
Commits created before the current run are still referenced
in the old way using a normal git commit.
