Bug fix.

Description:
Test failed when core and multi VFD is used.

SOlution:
Failure was because the test file was created with the specified VFD access
property but later reopened by default access. That won't work for VFDs such
as multi that produced files that are incompatible with the default sec2
file driver.

Fixed it by using the same VFD access property when it reopens the same test
file.

However, it still fails for the core VFD which does not create any real file.
It is meaningless to try to reopen its file.  Fixed it by adding core to
the incompatible list of VFDs so that it would skip the test.

Split is already coded as incompatible VFD but I don't understand why
it is incompatible in this case. Removed it from the incompatible list.

Tested Platforms:
Copper in which the daily test failed.
