Don't use "-c" flag in "git:branch-unique()" revision range rule
Don't use "-c" flag in "git:branch-unique()" revision range rule

Summary:
Fixes T9953.

  - "-c" was introduced in 1.7.2.
  - "--no-color" has existed forever as far as I can tell.
  - "--no-column" was introducd in 1.7.11, but there was nothing that needed to be disabled before that (hopefully).

Test Plan:
  - Ran `arc which --trace` and observed a reasonable `git branch` command with correct output.
  - Ran `arc which --trace` with a faked older Git version, observed command omit `--no-column`.
