No signature spoofing for user builds (and other non-debuggable build types) of 21.0 in restructured branch

[petefoth]

Upstream signature spoofing support is only for debuggable build types (e.g.userdebug). To make a user build (or other non-debuggable build types , our signature spoofing patches need to be applied.

This is not done in the pf-restructure-build branch, which is currently the only way to make 21.0 builds.

Workaround is to apply the patches manually. The code to do this is in this code in the master branch
