Work around git safe.directory enforcement

Git wants to ensure that you do not read .git owned by other users.
But we fetch+build as 'build' user, and run tests as root user.  Those
tests calculate git topdir using git rev-parse --show-toplevel, which
git now fails.

Setting safe.directory, seems wrong.  Let's just use bash to figure
out the top dir.
