Suppress LeakSanitizer in glibc DNS resolver (awslabs#301)

The allocation in `__res_context_send` is owned by glibc, which is supposed to clean it up at shutdown, but that seems to break occasionally. It's outside our control and a bounded allocation (once per process), so let's just ignore it. Signed-off-by: James Bornholt <[email protected]>
