zsh openrc compatibility

Replacing $BASH_SOURCE with ${BASH_SOURCE:-$0} makes devstack zsh friendly: in
bash, $BASH_SOURCE is used per usual; in zsh, where $BASH_SOURCE isn't
defined, $0 is used, which, unlike in bash, evaluates to the current
source file.

Now you can source devstack's openrc from a zsh shell.

Tested with bash and zsh from directories other than the root devstack
directory.
