[PATCH 05/31] hook.c: add a hook_exists() wrapper and use it in bugreport.c

[Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx>]

From: Emily Shaffer <emilyshaffer@xxxxxxxxxx>

Add a boolean version of the find_hook() function for those callers
who are only interested in checking whether the hook exists, not what
the path to it is.
