[PATCH] xfstests: log running test to dmesg

[Eric Sandeen <sandeen@xxxxxxxxxx>]

We already log the running test to system logs via "logger"
but viro pointed out that we can use /dev/kmsg to insert it
into dmesg as well.  When looking at the serial console that
could be pretty useful.

Thanks to viro for the test -w suggestion too.
