Bug 8924: Some modules erroneously skipped by 00-load

Bug 8924: Some modules erroneously skipped by 00-load

Several patterns were being skipped unnecessarily in t/00-load.t:
* C4::Cache* - no longer exists
* C4::Record - no longer requires database
* C4::Serials - no longer requires database

To test:
1) Unset KOHA_CONF and/or shut down MySQL.
2) Run `prove t/00-load.t`
3) If the test passes, the patch is good.
