Installing Chrome OS fonts fails when repo is on filer

install-build-deps.sh runs "sudo /path/to/src/build/linux/install-chromeos-fonts.py".
If the repo is on a filer, sudo fails because root is not allowed to access files on
a filer. However, installing a Repo on a Filer is not recommended.
Solution:
install-build-deps.sh attempts to detect that the Repo is not on a Filer and
in that case prints a warning with instructions.

Note: install-build-deps.sh exits immediately on failure because it uses "bash -e".
