Subject: util/gitconfig: Make gitconfig.sh support gitfile

The `gitconfig.sh` script installs hooks to the according directories
(for coreboot and its submodules). It has the `hooks` directory
hard-coded to be `.git/hooks`, which makes the installation fail when
coreboot itself is a submodule because then `.git` becomes a gitfile.

Replace hard-coded path handling using the according `git rev-parse`
calls.
