gnu: gdb@9.2: Restore 'gdb-hurd.patch'.

This patch got lost when e33c4286ebcc0dcc79985a32c6c2d5ad623d1fbe was merged
(commit 32787d652460871a79f99b63230f92759e2e0de2), but was still required on
the 'staging' branch.

* gnu/packages/patches/gdb-hurd.patch: New file.
* gnu/local.mk (dist_patch_DATA): Adjust accordingly.
