ANDROID: update is_cpu_allowed hook prototype

Browse Source 
Vendor module needs access to the task structure
through is_cpu_allowed tracehook to better
assess whether the chosen cpu can be allowed.

Update the existing is_cpu_allowed tracehook to
pass the task struct of the task currently being
handled.
