selftests/bpf: Fix xdp_synproxy compilation failure in 32-bit arch
xdp_synproxy fails to be compiled in the 32-bit arch, log is as follows:
xdp_synproxy.c: In function 'parse_options':
xdp_synproxy.c:175:36: error: left shift count >= width of type [-Werror=shift-count-overflow]
175 | *tcpipopts = (mss6 << 32) | (ttl << 24) | (wscale << 16) | mss4;
| ^~
xdp_synproxy.c: In function 'syncookie_open_bpf_maps':
xdp_synproxy.c:289:28: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
289 | .map_ids = (__u64)map_ids,
| ^
Fix it.
