Support core.hooksPath

[BuzzwordChief]

A global pre-commit hook (set with core.hooksPath) is ignored by gitui. It allows to commit the staged files even if the pre-commit hook returns with a non zero value.

To Reproduce
Create a pre-commit hook like this:

#! /bin/sh
exit 1

Expected behavior
the commit should fail, it doesn't.
