      Update dg-extract-results.* from gcc

dg-extract-results.sh was moved from the "gdb/contrib/" directory to
the toplevel "contrib/" directory.  However, src-release.sh was not
updated in order to include "contrib/" in the tarball release of GDB.
This makes it very inconvenient to run and analyze the GDB testsuite
results.  This commit adds "contrib/" to the list of support
directories that are included in each GDB release.
