Michael Ellerman 88893cf787 selftests: Print the test we're running to /dev/kmsg 
Some tests cause the kernel to print things to the kernel log
buffer (ie. printk), in particular oops and warnings etc. However when
running all the tests in succession it's not always obvious which
test(s) caused the kernel to print something.

We can narrow it down by printing which test directory we're running
in to /dev/kmsg, if it's writable.

Example output:

  [  170.149149] kselftest: Running tests in powerpc
  [  305.300132] kworker/dying (71) used greatest stack depth: 7776 bytes
                 left
  [  808.915456] kselftest: Running tests in pstore
