[PATCH v1] git-send-email: Respect core.hooksPath setting

[Robert Foss <robert.foss@linaro.org>]

get-send-email currently makes the assumption that the
'sendemail-validate' hook exists inside of the repository.

Since the introduction of `core.hooksPath` configuration option in
v2.9, this is no longer true.

Instead of assuming a hardcoded repo relative path, query
git for the actual path of the hooks directory.

This patch does not include a test for this bug fix.
This is entirely due to me not being able to think up a way
to test this. So I'm very much open to suggestions.
