[PATCH 3/9] sha1-name.c: move around the collect_ambiguous() function

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

A subsequent change will make use of this static function in the
get_short_oid() function, which is defined above where the
collect_ambiguous() function is now, which would result in a
compilation error due to a forward declaration.
