torture: Announce kernel boot status at torture-test startup 

Sometimes a given system takes surprisingly long to boot, for example,
in one recent case, 70 seconds instead of three seconds.  It would
be good to fix these slow-boot issues, but it would also be good for
the torture tests to announce that the system was still booting at the
start of the test.  Especially for tests that have a greater probability
of false positives when run in the single-CPU boot-time environment.
Yes, those tests should defend themselves, but we should also make this
situation easier to diagnose.

This commit therefore causes torture_print_module_parms() to print
"still booting" at the end of its printk() that dumps out the values of
its module parameters.
