Subject: [PATCH] extensionSystem: Use the system cert list

libsoup won't check for a valid cert by default, so copy some logic from
glib-networking to check against the system cert list. Additionally, allow a
fallback for developers, ~/.local/share/extensions.gnome.org.crt, for easy
local development of the website.
