[Review Queue] Charm testing: distcc, stackmobile, firefox-sync, shelrtv

[Cory Johns]

I did reviews of four charm testing / red-to-green merge proposals:

* distcc: -1 (install hook failure) (fixed)
* stackmobile: -1 (install hook failure) (SSL handshake error)
* firefox-sync: -1 (install hook failure)
* shelrtv: -1 (install hook failure) (PPA issue)

I was able to add a fix for the distcc charm, but the rest had
failures that are not clear how to resolve.
