[PATCH 5/6] [Outreachy] check-ref-format: parse-options

["george espinoza via GitGitGadget" <gitgitgadget@gmail.com>]

From: george espinoza <gespinoz2019@gmail.com>

This command currently handles its own argv so by teaching it to
use parse-options instead we can standardize the way commands
handle user input across the project.

Because OPT_BOOL data structure is being used on --normalize
--no-normalize can now be utilized.

NO_PARSEOPT flag was also removed to update git.c with the
conversion of the structure in this command.

I got all tests to pass at the moment. My next commit will be to
check if OPT_NEGBIT isn't needed and moving around OPT_VERBOSE.
