Fixed return from confirm so test acutally passes.
Using different directory for certs than pb_cipher_suites

There are different cert chains for pb_cipher_suites and http_security.
The certs were not fully cleaned between tests, so it would cause the
test to fail. By just using a different directory to put the certs into,
it better isolates the tests.
Removed reference to outdated add-map feature.
Added cacert to http_security path.

While r16b02-basho5 did not need the cacertfile path put in, r16b03 did.
The test still passes r16b02-basho5 with the added cacertfile line. Since
there is no harm in putting it in, better for forwards compatibility than
not.
Merge pull request #621 from basho/bugfix/mw/pb-cipher-suites-and-http-security

Change http_security uses different directory for certs then pb_cipher_suites
