selftests/bpf: Fix sockopt selftest failure on powerpc 



The SO_RCVLOWAT option is defined as 18 in the selftest header,
which matches the generic definition. However, on powerpc,
SO_RCVLOWAT is defined as 16. This discrepancy causes
sol_socket_sockopt() to fail with the default switch case on powerpc.

This commit fixes by defining SO_RCVLOWAT as 16 for powerpc.
