tests: fix regex in test-subrepo-git.t to match entire string
Due to a bug in the test runner (fixed by the next commit), the regex
used for matching lines like " foobar | 2 +-" stoppped at the "|" and
the test passed even though the rest of the line did not match. The
test seems to have been supposed to match "|" and "+" literally on
those lines, so this changes the regex to escape those characters. It
also changes a "\s*" to "\s+" since I think we'll always include a
space after the "|" in the diffstat output.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
