Bug 21115: Add multi_param call and add divider in cache key in svc/report and opac counterpart 

Resolve things like:
CGI::param called in list context from package CGI::Compile::ROOT::usr_share_koha_prodclone_opac_svc_report line 42, this can lead to vulnerabilities. See the warning in "Fetching the value or values of a single named parameter" at /usr/share/perl5/CGI.pm line 436.

The cache key in both script looks like:
    opac:report:id:602018
but should for consistency be:
    opac:report:id:60:2018
Note: The 2018 here is part of the sql_params and should not be
concatenated to the report id.

Test plan:
Do not yet apply this patch.
Make a report public, set cache to 300 secs.
Check its output with opac/svc/report.
Check for the warn in your log.
Apply the patch, restart Plack and flush cache.
Check opac/svc/report.
Modify your report; e.g. add a simple string to the SELECT.
Check opac/svc/report. You should still see cached output.
Flush the cache.
Check opac/svc/report. You should now see the added text.

Tested also by clearing individual keys with $cache->clear_from_cache.
