bash completion: Restore completion of available packages for 'guix build'.

Fixes a regression introduced in
9b0a755f642542dd96065ad05ec9d844d8077fd7 whereby 'guix build TAB' would
not suggest any completion.

* etc/completion/bash/guix (_guix_complete): Arrange so 'guix build TAB'
completes available packages.
