qio: add support for SO_PEERCRED for socket channel
The function qio_channel_get_peercred() returns a pointer to the
credentials of the peer process connected to this socket.
This credentials structure is defined in <sys/socket.h> as follows:
struct ucred {
pid_t pid; /* Process ID of the sending process */
uid_t uid; /* User ID of the sending process */
gid_t gid; /* Group ID of the sending process */
};
The use of this function is possible only for connected AF_UNIX stream
sockets and for AF_UNIX stream and datagram socket pairs.
On platform other than Linux, the function return 0.
