bpf: sockmap requires STREAM_PARSER add Kconfig entry
SOCKMAP uses strparser code (compiled with Kconfig option CONFIG_STREAM_PARSER) to run the parser BPF program. Without this config option set sockmap wont be compiled. However, at the moment the only way to pull in the strparser code is to enable KCM. To resolve this create a BPF specific config option to pull only the strparser piece in that sockmap needs. This also allows folks who want to use BPF/syscall/maps but don't need sockmap to easily opt out.
