Build system: Add fixes for scanbuild

- Exclude build flags that generate warnings when scanbuild is running
- Add the SCANBUILD_ARGS variable to abuild so we can pass in arguments
to scanbuild.
- Set the default scanbuild argument to -k (--keep-going) so that even
if an error occurs it continues with the scan.  This is similar to what
we do with coverity runs.
