mtp: support using pppox_socket family

Kernel commit da69a5306ab92e07224da54aafee8b1dccf024f6
("selinux: support distinctions among all network address families")
modified the kernel to support fine grain differentiation of socket
families, if userspace enables it (which Android does).

Modify the mtp SELinux policy to allow the use of pppox_socket
(needed for kernels 4.14 or greater) and the generic "socket" family
(for kernels below 4.14).
