perf intel-pt: Fix segfault in intel_pt_print_info() with uClibc
uClibc segfaulted because NULL was passed as the format to fprintf().
That happened because one of the format strings was missing and
intel_pt_print_info() didn't check that before calling fprintf().
Add the missing format string, and check format is not NULL before calling
fprintf().
Fixes: 11fa7cb86b56d361 ("perf tools: Pass Intel PT information for decoding MTC and CYC")
