contrib: Add KPASS support to dg-extract-results.{sh,py}

Extend dg-extract-results.sh and dg-extract-results.py to support the
KPASS test result status.  This is required by GDB which uses a copy
of the dg-extract-results.{sh,py} scripts that it tries to keep in
sync with GCC.

ChangeLog:

        * contrib/dg-extract-results.sh: Add support for KPASS.
        * contrib/dg-extract-results.py: Likewise.
