MFC r311893, r313008, r313081

I had to modify the tests slightly for the MFC to stable/10, because
stable/10 lacks r294037, which enabled /sbin/md5 to work on md(4)
devices.

r311893:
ATFify the geom gate tests.

This ensures their cleanup routines will be run even if they should timeout.

tests/sys/geom/class/gate/ggate_test.sh
tests/sys/geom/class/gate/Makefile
	Add an ATF test with three testcases, one for each TAP test. Use
	ATF-style cleanup functions, and convert sleeps to polling loops.

tests/sys/geom/class/gate/conf.sh
tests/sys/geom/class/gate/1_test.sh
tests/sys/geom/class/gate/2_test.sh
tests/sys/geom/class/gate/3_test.sh
	Delete TAP test files

r313008:
Wait for /dev/ggate* to appear after calling `ggatel create` in :ggatel_{file,md}

The test assumed that `ggatel create` created a device on completion, but that's
incorrect. This squashes the race by waiting for the device to appear, as
`ggatel create` daemonizes before issuing an ioctl to geom_gate(4) if not called
with `-v`.

r313081:
Replace for/retry loops with "wait_for_ggate_device" calls and check
results of commands

As noted in r313008, the underlying issue was that geom_gate device
creation wasn't created at ggatel command completion, but some short
time after. ggatec(8) employs similar logic when creating geom_gate(4)
devices.

Switch from retry loops (after the ggatec/dd write calls) to
wait_for_ggate_device function calls after calling ggatec(8) instead
to detect the presence of the /dev/ggate* device, as this function is
sufficient for determining whether or not the character device is ready
for testing

While here, use atf_check consistently with all dd calls to ensure that
data output is as expected.
