[PATCH 2/4] gdb/testsuite: Factor out dg-extract-results.sh calls

The parallel-testing targets in the testsuite Makefile each combine
the per-test gdb.sum / gdb.log files produced by a run into a single
combined pair, using contrib/dg-extract-results.sh.  The same pair of
invocations (once for gdb.sum, once with -L for gdb.log) is copied in
check-parallel, check-parallel-racy, and check-all-boards, each only
differing in the input and output directories.

Factor those invocations into a DG_EXTRACT_RESULTS canned recipe
parameterized by the input and output directories, and use it from all
three targets.
