bpf: Avoid old-style declaration warnings

bpf: Avoid old-style declaration warnings

gcc -Wextra wants type modifiers in the normal order:

kernel/bpf/bpf_lsm.c:70:1: error: 'static' is not at beginning of declaration [-Werror=old-style-declaration]
   70 | const static struct bpf_func_proto bpf_bprm_opts_set_proto = {
      | ^~~~~
kernel/bpf/bpf_lsm.c:91:1: error: 'static' is not at beginning of declaration [-Werror=old-style-declaration]
   91 | const static struct bpf_func_proto bpf_ima_inode_hash_proto = {
      | ^~~~~

Fixes: 61db6b0d6088 ("bpf: Add bpf_bprm_opts_set helper")
Fixes: 4655c3bf185b ("bpf: Add a BPF helper for getting the IMA hash of an inode")
