Bug 11329: Check for MARC record existence in opac-showmarc

Instead of just running as_formatted, check if GetMarcBiblio returned
a reference. If you e.g. did not pass an id, return 404 instead of 500.
Consistent with opac-export.pl

Test plan:
[1] Run opac-showmarc.pl with valid biblionumber in id parameter.
[2] Remove id parameter from URL. You should get a 404 now.
