Nikos Dragazis d1152a200f test: Add test to validate SSTables with no checksums
In a previous patch we extended the return status of
`sstables::validate_checksums()` to report if an SSTable cannot be
validated due to a missing CRC component (i.e., CRC.db does not appear
in TOC.txt).

Add a test case for this.
