Subject: [PATCH] scripts: dev-needs.sh: Enforce bash usage

Calling the script from a system which does not invoke bash
by default causes a return with a syntax error like:

	./dev-needs.sh: 6: Syntax error: "(" unexpected

/bin/sh invokes on most distributions a symbolic link to a
default shell like dash (Debian) or bash (Ubuntu).

Since the script depends on bash syntax, enforce the same by
default to prevent syntax errors caused by wrong shell type usage.
