alarmtimer: Export symbols of functions declared in linux/alarmtimer.h 

Export symbols so they can be used by
drivers/staging/android/alarm-dev.c if it is built as a module.
So far alarm-dev is built-in but module support is planned (see
drivers/staging/android/TODO).

[jstultz: tweaked commit message, also export newly added functions]
