[PATCH v2 2/5] commit-graph: remove redundant handling of -h

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

If we don't handle the -h option here like most parse_options() users
we'll fall through and it'll do the right thing for us.

I think this code added in 4ce58ee38d (commit-graph: create
git-commit-graph builtin, 2018-04-02) was always redundant,
parse_options() did this at the time, and the commit-graph code never
used PARSE_OPT_NO_INTERNAL_HELP.
