Bug 8383: Add test to check that Perl scripts compile

This patch adds t/db_dependent/00-strict.pl which tests that all Perl
scripts compile. I chose to use Test::Strict so that in the future we
can also have the test check that "use strict" and "use warnings" are
enabled.

To test:
1. Run t/db_dependent/00-strict.pl.
2. Run around waving your arms in the air that we have a couple of
   scripts that don't compile.
3. Actually, that's about it. You could test my patch for bug 8384 next.
