daemon: Make dependency on storaged resolved at runtime

Soon we'll be calling storaged and udisks directly from javascript
code. The module that the javascript code lives in should be built
in a package that depends on storaged and udisks so it's appropriately
installed.

We won't be using the interface xml directly anymore anyway. So
this is an interim step, in the right direction, even though it looks
like a hack.

common, bridge: Support older JSON versions like 0.14.2

This is compatible on RHEL6 and other OS's. We just needed
a few minor changes to make this work.

We expect json-glib 0.14.0 or later, but I accidentally used
functions only available in later versions.

Use shell.xxxx instead, once we start mixing components using
