[Outreachy PATCH v2 2/2] git.c: drop NO_PARSEOPT from builtins that use parse-options

[Tanga Joris <tangajoris@gmail.com>]

The NO_PARSEOPT flag in the commands[] table marks builtins that
parse their options by hand. Builtins marked with it are left out
of "git --list-cmds=parseopt", which bash completion uses to
decide whether it can ask a command for its options with
"--git-completion-helper".

Four builtins have since been converted to parse-options, but are
still marked NO_PARSEOPT:

 - patch-id, in 2871f4d447 (builtin: patch-id: add --verbatim as a
   command mode, 2022-10-24)
 - diff-pairs, which has used parse-options since it was introduced
   in 5bd10b2adc (builtin: introduce diff-pairs command, 2025-02-28)
 - fast-import, in 863937696e (fast-import: use parse_options() for
   command line options, 2026-08-11)
 - var, in e19f0779c6 (var: add "-z" output mode, 2026-09-26)

This causes "git fast-import --<TAB>", "git patch-id --<TAB>" and
"git diff-pairs --<TAB>" to offer no options, even though they are
listed by "--git-completion-helper".

Remove the flag from these four builtins, like 66fa6e8ed8 (git.c:
update NO_PARSEOPT markings, 2022-08-19) did for others.
