Subject: bpf: remove CONFIG_BPF_JIT dependency on CONFIG_MODULES of
Date: Mon, 18 Sep 2023 10:29:55 +0300
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.

BPF programs are normally handled by a BPF interpreter. This option
allows the kernel to generate native code when a program is loaded
