Subject: [PATCH] Bug 17385: (QA follow-up) Do not needlessly scan biblioexport
 folder

Performance: We need to return an empty list if OpacExportOptions does not contain Custom.  No need to scan the directory for custom files, if we are not using them at all.

Note: The test only pertains to OPAC now, since the pref should not control intranet behavior. We have no intranet counterpart. See further next follow-up.

Test plan:
Run t/db_dependent/XSLT.t
