cvsimport: add <remote>/HEAD reference in separate remotes more

When in separate remote mode (via -r <remote>) we can now use
the name HEAD for the CVS HEAD.  In keeping with git-clone
remotes/<remote>/HEAD is creates as a symbolic ref to the user
specified name for the HEAD which defaults to master.
