softlockup: make DETECT_HUNG_TASK default depend on DETECT_SOFTLOCKUP

Don't offer a default-y option when the user has turned off
CONFIG_DETECT_SOFTLOCKUP already.

Do offer it as 'y' only if DETECT_SOFTLOCKUP is on already.

This makes it match previous behavior - where the hung-task check was
embedded i CONFIG_DETECT_SOFTLOCKUP code.
