SCons: Treat all warnings as errors 

After an effort spanning several years, we should now be warning-free
on all major compilers, so we can set `-Werror` to ensure that we don't
introduce warnings in new code.

Disable -Werror=strict-overflow on GCC 7 though, as it seems bogus and
was fixed in 8+.
