selftests: timers: clocksource-switch: Adapt progress to kselftest framework

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.

selftests: timers: clocksource-switch: adapt to kselftest framework

So we have proper counters at the end of a test. We also print the
kselftest header at the end of the test, so we don't mix with the output
of the child process. There is only this one test anyhow.

selftests: timers: clocksource-switch: fix passing errors from child

The return value from system() is a waitpid-style integer. Do not return
it directly because with the implicit masking in exit() it will always
return 0. Access it with appropriate macros to really pass on errors.
