Exclude .tmp_git_root from globs

This directory contains the original git repo when the crate is from git. Including this directory currently makes these rules re-run whenever the repository rule re-runs, although this is fixed by bazelbuild/bazel#18271. Even after this fix, excluding this directory avoids depending on unnecessary files.

Fixes bazelbuild#1927.
