bpf: Add bpf_ksym_add/del functions
Separating /proc/kallsyms add/del code and adding bpf_ksym_add/del functions for that. Moving bpf_prog_ksym_node_add/del functions to __bpf_ksym_add/del and changing their argument to 'struct bpf_ksym' object. This way we can call them for other bpf objects types like trampoline and dispatcher.
