bitbake: build/data: Write out more complete python run files
Currently the output in the python task/function run files is rather incomplete and effectively useless. This enhances the code to take advantage of the bitbake's dependency tracking and extend the output to include dependencies. This makes the files more usable for debugging purposes. Since this only happens at python function execution time, the overhead is minimal in the grand scheme of things. (Bitbake rev: 02667e048c3e632f857c87177c0022eaf5481802) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
