Silence bashate

The remaining bashate warnings was E042:
 The return value of "local" is always 0; errors in subshells
 used for declaration are thus hidden and will not trigger "set
 -e".

Fix the few cases this triggered so that we don't get confused anymore
about the message.

Remove -v from bashate invocation, we don't need to print out all the
filenames anymore.
