Use named volumes for docker pkg cache

Browse source 
Changes the default when incremental build is enabled to use named
volumes instead of bindmounts.
The reason for this is, on Mac/Windows the bind mounts will go over the
shared fs, which is incredibly slow and itself uses lots of CPU.

Makes an incremental build on OSX go from ~40s to 10s.

To get the old behavior, can set `PKGCACHE_DIR=.go-pkg-cache`
