Bug 30147: Fix modules usage in opac-detail.pl

On the ktd sample database when trying to go to the detail page from the result list:
Undefined subroutine &CGI::Compile::ROOT::kohadevbox_koha_opac_opac_2ddetail_2epl::searchResults called at /kohadevbox/koha/opac/opac-detail.pl line 260
Turning off OpacBrowseResults makes the error disappear.

In opac-detail.pl, use C4::Search is missing searchResults and getRecords

To test:
- Search for something that gives several result pages in OPAC, example: e
- Switch to one of the last pages using link on top of results, example: 10
- Open any of the records listed in detail view
- Verify that the error is shown
- Apply patch and repeat, error is gone and browsing behaves as expected
