ANDROID: GKI: cputime: Export for thread_group_cputime_adjusted

Browse Source 
- Add EXPORT_SYMBOL_GPL for thread_group_cputime_adjusted()
    to allow drivers to be loadable as a module.

    - This API is required by loadable driver module from samsung
    to fetch process uptime based on CPU clock ticks to get the
    exact duration of time app is scheduled in user mode.
