generic/085 was failing on a machine w/o devicemapper kernel
support because it requires the linear target, but didn't
explicitly test for it.
I could have cut & pasted _require_dm_linear(), but chose
to go the route of a generic helper, _require_dm_target $FOO,
because some day someone will need the zero target, the error
target, or who knows.
Add the helper, use it in test generic/085, and convert
_require_dm_flakey, _require_dm_snapshot, and
_dmerror_required with this new helper.

This test case tests if the device delete works with
the failed (EIO) source device. EIO errors are achieved
usign the DM device.
This test would need following btrfs-progs and btrfs
kernel patch
btrfs-progs: device delete to accept devid
Btrfs: device delete by devid
However when btrfs-progs patch is not found this test will
not run, and when kernel patch is not found btrfs-progs
will fail gracefully and thus the test script.
