git-prompt: change == to = for zsh's sake

When using git-prompt.sh with zsh, __git_ps1 currently errs
when inside a repo with:

__git_ps1:96: = not found

Avoid using non-portable "==" that is only understood by bash
and not zsh. Change to "=" so that the prompt script becomes
usable with zsh again.
