disk_cache: reduce default cache size to 5% of filesystem

Browse source 
Modern disks are extremely large and are only going to get bigger.
Usage has shown frequent Mesa upgrades can result in the cache
growing very fast i.e. wasting a lot of disk space unnecessarily.

5% seems like a more reasonable default.
