bin/brew: remove bash redirection (#889)

This was added back then to allow to run brew if you had no /bin/bash.
There are now multiple places in the code where /bin/bash is hardcoded,
which makes this change useless without fixing the other places.

If needed we can try to provide a better solution later on, but I think
removing this allows to have one patch less to backport to Homebrew.
