libcutils: use 0 for netlink socket port id
AudioHAL and SoundtriggerHAL is separeted HAL but running in thread with
same process id.
So, if both HAL try to open netlink socket using uevent_open_socket(),
secondly opening socket receives already-in-use error.
To prevent situation, set 0 to socket port id.
By the LINUX man page, "The kernel assigns the process ID to the first
netlink socket the process opens and assigns a unique nl_pid to every
netlink socket that the process subsequently creates."
Bug:163008274
Test: tested by opening netlink socket in AudioHAL and
SoundtriggerHAL both.
