We are making a change to uevent_open_socket() in libcutils related to
setting the receive buffer size of netlink uevent sockets.
After setting SO_RCVBUF, we immediately read it back using getsockopt()
to verify that the setsockopt() call was effective. Only if it was not
effective, we call setsockopt() with SO_RCVBUFFORCE.
getsockopt() previously caused SELinux denials like the following:
avc: denied { getopt } for comm="usb@1.1-service" scontext=u:r:hal_usb_default:s0 tcontext=u:r:hal_usb_default:s0 tclass=netlink_kobject_uevent_socket permissive=0
