[PATCH 11/27] read-cache: convert post-index-change hook to use config

[Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx>]

From: Emily Shaffer <emilyshaffer@xxxxxxxxxx>

By using hook.h instead of run-command.h to run, post-index-change hooks
can now be specified in the config in addition to the hookdir.
post-index-change is not run anywhere besides in read-cache.c.

This removes the last direct user of run_hook_ve(), so we can make the
function static now. It'll be removed entirely soon.
