Bug 1476408 - No longer necessary to run lint_config.sh anymore; r=TD-Linux

Summary:
Upstream can now code generate the rtcd interface files directly from the
aom_config.h header, so we no longer have to generate an intermediate file by
running lint_config.sh. This also means we can remove the code for creating a
temporary directory.
