Export all the relevant generic netlink information to user-space to make this genl family usable by user-space, and while at it, export THERMAL_NAME_LENGTH since it limits name length for thermal_hwmon devices. Kbuild and MAINTAINERS are also updated accordingly to reflect this new file: include/uapi/linux/thermal.h.
