When "bitbake -k -S none world" failed, the error printed by
yocto-compat-layer.py contained the stack trace multiple times and did not
contain the stderr output from bitbake, making the error hard to understand
and debug:
INFO: ======================================================================
INFO: ERROR: test_signatures (common.CommonCompatLayer)
INFO: ----------------------------------------------------------------------
INFO: Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Summary: There were 5 ERROR messages shown, returning a non-zero exit code.
The yocto-compat-layer.log was incomplete, it only had the first part
without the command output.
stderr was missing due to stderr=subprocess.PIPE.
Instead of the complicated try/except construct it's better to check
the return code ourselves and raise just a single exception. The
output (both on stderr and in the yocto-compat-layer.log) now is:
