s390/decompressor: print cmdline and BEAR on pgm_check
Add kernel command line and last breaking event.
The kernel command line is taken from early_command_line and printed
only if kernel is not running as protected virtualization guest and
if it has been already initialized from the "COMMAND_LINE".
