t5703: refactor test to not depend on Perl

We use Perl due to two different reasons in t5703:

  - To filter advertised capabilities.

  - To set up a CGI script with HTTPD.

Refactor the first category to use `test_grep` instead. Refactoring the
second category would be a bit more involved, so instead we add the
PERL_TEST_HELPERS prerequisite to those individual tests now.
