use -R default instead of -R=-default for ctest

- the change from 821ba2b breaks the target for older ctest versions,
  i.e., the regex doesn't get applied and all or many many more tests than
  "*-default*" are run
- with -R -default not working for ctest 4 and -R=-default not working for
  ctest 3, this now relaxes the filter to -R default
