convert: pass absolute paths to git (SEC)

Fixes CVE-2016-3105 (1/1).

Previously, it was possible for the repository path passed to git-ls-remote
to be misinterpreted as a URL.

Always passing an absolute path to git is a simple way to avoid this.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
