Bash completions: add __brewcomp_prev 

Previously, __brewcomp_prev function was provided in Homebrew/brew Bash
completion script. It was removed in Homebrew/brew#14545 because no
other function in Homebrew/brew was using it. Since Bash completions for
Homebrew/services relies on this function, we restore __brewcomp_prev
here.
