buildtools: Use separate storage for each function in runonce

Browse Source 
The runonce decorator used shared storage for all functions, and
dispatched only on arguments, so a call would be eliminated if
a different runonce function had already been called with the same
arguments.

Use separate storage for each decorated function.
