Sandbox soong_build by changing to root directory
This relands I12a0f907753fefd1997ab8b4ea2ac331234093cf along with
a fix to blueprint for absolute paths.
Store the current working directory and then change to the root
directory so that all file accesses must go through helpers in
the android package that properly track dependencies.
