lib/core: Use igt_info instead of printf

igt_info doesn't add anything when printing to stdout, but so looks
the same. But it has the upside of appending the lines also to the igt
crashdump log, where I especially want the backtraces. Atm they're the
only thing that doesn't end up in there, which is a bit confusing.

While at it also convert the other lines - the test summary usually
doesn't make it since the test fails before that, and the version line
tends to scroll off the crashdump.
