Update Salt's virtualenv settings

1) no_site_packages option has been deprecated for system_site_packages
2) if the requirements file has references to other requirement files on the file system, Salt will break unless no_chown option is given which prevents Salt from copying the requirements file to /tmp/ before running.
Make uWSGI directory apps-available.

Not sure if something changed in PyPI or Ubuntu packages, but the
/etc/uwsgi/apps-available directory stopped being auto-created
which causes other uWSGI salt tasks to fail.

Updated Vagrantfile for trusty and other tweaks.

First and foremost this is an update to trusty rather than precise.  I switched
salt to its stable release since there did not seem to be daily builds for
trusty (at least not at that PPA).

I also changed the VM to use two CPUs and 1GB of memory, perhaps
unnecessariliy.

I added the ability to cache deb files.
