From: "Mike Rapoport (IBM)" <[email-masked]>

BPF just-in-time compiler depended on CONFIG_MODULES because it used
module_alloc() to allocate memory for the generated code.

Since code allocations are now implemented with execmem, drop dependency of
CONFIG_BPF_JIT on CONFIG_MODULES and make it select CONFIG_EXECMEM.
