  When adapting the test to the kselftest framework, a few printf() calls
indicating test progress were not updated.

Fix this by replacing these printf() calls by ksft_print_msg() calls.

When just running the test, the output looks like:

    # Validating clocksource arch_sys_counter
    TAP version 13
    1..12
    ok 1 CLOCK_REALTIME
    ...
    # Validating clocksource ffca0000.timer
    TAP version 13
    1..12
    ok 1 CLOCK_REALTIME
    ...

When redirecting the test output to a file, the progress prints are not
interspersed with the test output, but collated at the end:

    TAP version 13
    1..12
    ok 1 CLOCK_REALTIME
    ...
    TAP version 13
    1..12
    ok 1 CLOCK_REALTIME
    ...
    # Totals: pass:6 fail:0 xfail:0 xpass:0 skip:6 error:0
    # Validating clocksource arch_sys_counter
    # Validating clocksource ffca0000.timer
    ...

This makes it hard to match the test results with the timer under test.
Is there a way to fix this?  The test does use fork().

Thanks!
