If "branch" is provided to "diffusion.branchquery", use it as the "<pattern>" argument to "git branch --contains ..."

Browse source 
Summary:
Ref T13151. See PHI720. If you want to test if commit X appears on specific branch Y, `git branch --contains X -- Y` is faster than (effectively) `git branch --contains X | grep Y`.

Since this call has a "branch" parameter anyway, use it as the pattern argument if provided.

Test Plan:
  - Called the API method with no parameters, got all branches.
  - Called the API method with `master`, got just master.
  - Called the API method with `maste*`, got master. This behavior is not officially supported and may change in the future.
  - Viewed a commit, still saw all branches.
    - Grepped for `diffusion.branchquery` and verified that no remaining callsites pass a default "branch" parameter.
