lib/tsocket: workaround sockets not supporting FIONREAD
Netlink sockets don't support querying pending bytes with ioctl(fd,
FIONREAD, ...) and would return EOPNOTSUPP, so use recvmsg() with
MSG_PEEK|MSG_TRUNC as a fallback.
The MSG_TRUNC flag to recvmsg() is Linux only, but netlink is as well,
so we're safe for now.
