build: use /usr/bin/env to load bash

On BSD platforms, there is a clear seperation between the OS and third
party packages. Here, bash is a third party package so it won't be
installed to /bin.

FreeBSD:	/usr/local/bin/bash
NetBSD:		/usr/pkg/bin/bash
OpenBSD:	/usr/ports/bin/bash

As such, we need to use /usr/bin/env to launch these scripts.
