tests: Add core backtracegen check and regen ppc32 backtrace testfiles.
Add a check to check_core to make sure the backtracegen function is
found in the backtrace. This function is in the middle of the backtrace
in the main executable and if not found it means the backtrace was
incomplete or the frame was skipped (which could happen on a bad frame
pointer only unwind).
This showed that the ppc32 backtrace test files were missing DWARF CFI
for the main executable. Regenerated them to include full CFI.
