kernel/hung_task convert hung_task_panic boot parameter to sysctl
We can now handle sysctl parameters on kernel command line and have
infrastructure to convert legacy command line options that duplicate
sysctl to become a sysctl alias.
This patch converts the hung_task_panic parameter. Note that the sysctl
handler is more strict and allows only 0 and 1, while the legacy
parameter allowed any non-zero value. But there is little reason anyone
would not be using 1.
