build: move incremental decision into options

Currently build.Options returns a list of indexed versions. This is used
in each command to decide if we should incrementally index. However, it
has been updated over time to also do extra checks for incremental
indexing. If one of those checks fail, it returns nil to force the
indexing.

This commit updates the function to encapsulate what we want, the
decision of should we index given the build options.
