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.
