Revert "Suppress all progress messages from Ninja if ANDROID_QUIET_BUILD is set."

Reverts commit 827aead3
The change being reverted is the result of misunderstanding of how the
status system works. It has to be reverted because it would suppress
_all_ error messages from Make. Achieving what this change purports is
is more involved and requires changing the code to separate progress message
stream from application output stream.

Test: run failing build with ANDROID_QUIET_BUILD=tree and observe errors being output
