Integrate tools/regression/fifo into the FreeBSD test suite as tests/sys/fifo

Integrate more tests into the FreeBSD test suite from tools/regression, etc

Check fchmod()/fchown() in fifo_misc test.

fifo_misc test: Fix swapped lseek arguments.

It worked regardless because SEEK_CUR happens to be 1.

The devices that supported EVFILT_NETDEV kqueue filters were removed in
r195175. Remove all definitions, documentation, and usage.

fifo_misc.c:
Remove all kqueue tests as fifo_io.c performs all those that
would have remained.

o Test truncate(2) on fifo: it should ignore the request and
return success.

PR: kern/98064
Submitted by: Kirk Russell

Add two small tests to set and clear two file I/O flags using ioctl on
a fifo: FIONBIO, FIOASYNC.

Remove a debugging printf.

Comment test_lseek().

Add test_kqueue(), which registers and unregisters various kqueue filter
types on a fifo in order to make sure that EVFILT_READ, EVFILT_WRITE can
be registered, and that EVFILT_NETDEV can't be registered. For now, we
don't test that EVFILT_VNODE can be registered on fifos, as that has been
broken at some point.

Add fifo_misc, a regression test to hold misc. functional tests for fifos
that don't obviously fit into create, open, and io. For now, add only a
regression test to make sure that lseek() fails with ESPIPE (which it
doesn't).
