Rely on git to find the root directory.

Using `rev-parse --show-toplevel` we can find the top directory. Since
we've set the '-e' option for bash, if we're not in a git repository
this will fail (which is what we want).

Add a few quotes and upper case a variable.

Make the shell style more consistent.

The style was inconsistent, using sometimes 4 spaces or 2 spaces for
indentation; using 'then' on the same line or another line; some
variables were quoted correctly; etc.

The style is now consistent and it's easier to read the script.

Instead of blindly running `sysctl`, only do it if we're on Linux.
