The 3 tests that _require_xfs_io_command "flink", actually require
O_TMPFILE support and flink command, but the former is far unlikely
to be missing. The test btrfs/058 doesn't even use the flink command.

When running these tests on a filesystem that does not support O_TMPFILE
(e.g. overlayfs) the result is not very infomative:

 generic/004 1s ... [not run] xfs_io flink failed (old kernel/wrong fs?)

Decouple the requirements for "flink" command and "-T" command line flag
and require the former explicitly in tests that use it.

As a result the report is now more informative:

 generic/004 1s ... [not run] O_TMPFILE is not supported
