Override module's C flags when coverage is enabled
Bug: http://b/116873221
Disable -Wframe-larger-than because building without optimization can
make frame larger. Building dng_sdk with coverage results in a bigger
stack frame than the limit in C flags.
Get optimization level back to -O0 if module has a non-default
optimization level. Not doing so causes link failures with
libneuralnetworks.so.
Test: Build with coverage.
