[PATCH v2 7/9] builtin/send-pack.c: Use option parsing API

[Dave Borowitz <dborowitz@google.com>]

The old option parsing code in this plumbing command predates this
API, so option parsing was done more manually. Using the new API
brings send-pack more in line with push, and accepts new variants
like --no-* for negating options.
