nucleus/shadow: disable u_mode watchdog for 2.4.x kernels
The u_mode consistency watchdog has false positive triggers due to
obsolete glibc limitations wrt pthread key deletion upon app
exit.
Disable the u_mode watchdog when a 2.4.x kernel is detected, assuming
an old glibc is likely at work as well.
