Add tests for lowpay and dius
Explicitly run in bash
Don't run some businesslink tests on bouncer

Bouncer doesn't currently support the complex canonicalisation rules 
which are needed for some of the businesslink mappings to work. See
lib/Mappings/Businesslink.pm for the rules I'm referring to.

Therefore let's disable it for bouncer until we need bouncer to
serve/support businesslink.
Skip DG/BL tests against Bouncer for now

We need a passing smokey suite for Bouncer, but we don't plan to support
businesslink and directgov mappings for a while because they are complicated.
