ANDROID: vendor_hook: rename the the name of hooks

Browse source 
Renamed trace_android_vh_binder_detect_low_async_space_locked to
trace_android_vh_binder_detect_low_async_space.

Because the orignal name is too long, which results to the
compile-err of .ko that uses the symbol:

ERROR: modpost:
too long symbol "__tracepoint_android_vh_binder_detect_low_async_space_locked"

There is not any users of the the orignal hooks so that it is safe to
rename it.
