add SQLT dep if DBICTEST_SQLT_DEPLOY env is set

Add some code to Makefile.PL to check for $ENV{DBICTEST_SQLT_DEPLOY},
which if set requires SQL::Translator to be available or the tests
will fail. Add the dep as a test_requires directly, so that it is
scrubbed out of the META.yml in author mode due to not being in the
$test_requires hash.
