bpf: Add zero_map_value to zero map value with special fields
We need this helper to skip over special fields (bpf_spin_lock,
bpf_timer, kptrs) while zeroing a map value. Use the same logic as
copy_map_value but memset instead of memcpy.
Currently, the code zeroing map value memory does not have to deal with
special fields, hence this is a prerequisite for introducing such
support.
