Support disabling the repository cache

Support disabling the repository cache in cases where caching is
not necessary, but the additional disk operations are a problem.
This is achieved by interpreting --repository_cache= as a request
to disable the cache; technically, this is an incompatible change,
as currently the empty string is interpreted as "put the cache
top-level into the workspace". However, it is unlikely that this
use of the option is widely used.

Fixes #6229.
