Use named volumes for docker pkg cache

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`
