btrfs-progs: mkfs-tests: ensure regular builds won't enable rst feature

This test case will check the following behviour:

- Regular zoned supported data/metadata profiles
  Should success

- RST with zoned feature
  Should fail for non-experimental builds

- zoned with data profiles that only RST supports
  Should fail for non-experimental builds.

  Meanwhile for experimental builds it should success and enable RST
  feature automatically (verified in mkfs/030)
