Mauricio Vasquez B c9d29f4658 bpf/syscall: allow key to be null in map functions
This commit adds the required logic to allow key being NULL
in case the key_size of the map is 0.

A new __bpf_copy_key function helper only copies the key from
userpsace when key_size != 0, otherwise it enforces that key must be
null.
