Bug 40006: Add option to avoid doing a git checkout when using the exec template function

The `exec_noco` option can be used to disable git or hg checkout when
using the exec template function.

We start using this option in the `abbrev` and `timestamp` options,
which are running git and hg commands which don't need a checkout.
