contrib: Update dg-extract-results.* from gcc

The dg-extract-results scripts have been updated in the gcc
repository.  This commit copies the updated versions of the scripts in
to the binutils-gdb repository.

There are two changes, these are:

  1. Improved detection of timeout lines, though I suspect this only
  applies to gcc results, and

  2. Detection of KPASS results, this is of interest to gdb, where
  these results would not be included in the final .sum file.

A grep over binutils-gdb shows the dg-extract-results is not used by
ld, gas, or binutils, however I tested these anyway and saw no changes
in the final .sum files (tested on x86-64 GNU/Linux).

On gdb when running tests in parallel dg-extract-results is used, and
the final .sum file now includes the KPASS results.

contrib/ChangeLog:

	* dg-extract-results.py: Update from gcc repo.
	* dg-extract-results.sh: Likewise.
