Fix UDP GRO/GSO tests.
1. The GRO test was failing on new kernels. This is because
getsockopt(IPPROTO_UDP, UDP_GRO) is not supported: the option
can only be set, not get. Don't attempt to get it.
2. The GSO test was failing on older kernels because it fetched
the kernel version as a double and then compared it against
4.19. This fails on 4.9 and 4.4 kernels because 4.19 < 4.4.
Fix this by fetching the kernel version as a 2-int array
instead of a single double.
