manifestcache: use `wcache` directory for manifest cache

The manifest full text cache is tightly related to the working copy. We should
use the `wcache` directory for it, instead of the `cache`. Otherwise, multiple
shares would keep overwriting each other cache entry and we loose its benefit.

This is also more consistent with the fact this cache file is protected by
`wlock`.
