Due to bpf_map_lookup_elem being declared static we need to also declare subprog_noise as static.

Fixes the following error: progs/tailcall_bpf2bpf4.c:26:9: error: 'bpf_map_lookup_elem' is static but used in inline function 'subprog_noise' which is not static [-Werror] 26 | bpf_map_lookup_elem(&nop_table, &key); | ^~~~~~~~~~~~~~~~~~~
