The bundles dir used to be automatically made a volume if BINDDIR was
not set.
The `PKGCACHE_*` stuff was added recently which gets added to
`DOCKER_MOUNT`. This breaks the case where someone wants to use the
package cache (DOCKER_INCREMENTAL_BINARY is enabled) but has not
specified a bind dir but needs the bundles dir made a volume.
Moves the package cache handling to after the bundles dir is made a
volume.
Before this patch, if you have `DOCKER_GRAPHDRIVER` set to anything
other than vfs, the tests in the daemon suite (and swarm suite, and
registry suite) will fail to run since they cannot startup a daemon
(except for speicifc cases where <driver> over <driver> is possible,
like devmapper).
