generic/740: enable by default

Instead of limiting this test to a few file systems, opt out the
file systems supported in common/rc that don't support overwrite
checking at all, and those like extN that support it, but only when
run interactively.

Also remove support for really old mkfs.btrfs versions that lack
the overwrite check.
