clover: Unify program::build_* into a single method returning a struct.

This gets rid of the program::build_* query methods and replaces them
with the program::build() method that returns a single data structure
containing all parameters for the last build done on the given target
device (including build logs, options and the binary itself).

[ Serge Martin: Fix inverted opts and log build ctor args ]
