binman: Do not pollute source tree when build with `make O=...`
Importing libraries in Python caches the bytecode by default.
Since we run scripts in source tree it ignores the current directory
settings, which is $(srctree), and creates cache just in the middle
of the source tree. Move cache to the current directory.
