extensions: Allow updating with only extension-manager installed

GNOME Shell will only update extensions if the org.gnome.Extensions
app is present. This commit adds alternative support for
com.mattjakeman.ExtensionManager to the extension updating mechanism.

It enables updates to occur when extension-manager is the sole installed
tool on the system. When both applications are installed,
org.gnome.Extensions is preferred at all times.

Fixes #5564
