Swapping order of performance and release testing on bradc-lnx

Performance testing has been growing slightly in time recently, so
let's run it before release testing to minimize the chances that it's
still coming when I come in and start disturbing my machine.

Longer-term, we've discussed having the normal correctness testing run
from the release tarball and mixing other aspects of the test release
script into a smoketest after the creation of the release tarball.
