btrfs-progs: convert: add raid-stripe-tree to allowed features

The raid-stripe-tree can be enabled for convert, though it's still
considered incomplete and slightly experimental. Due to that the tests
need to be adjusted to check for support and skip mount eventually.

Possible remaining options to add: quota, squota
