Subject: Use soong_ui directly, instead of make

This will use ckati instead of make for dumping variables, for
consistent makefile parsing. It may also sandbox executions, etc.

Also skip the legacy make wrapper to build, and use soong_ui instead.
The command line arguments are equivalent, but -j is no longer
necessary, we'll default to a sane value.

Test: bit -b framework
