glib: Namespace global tapset variables by soname

Browse Source 
global variables in SystemTap are shared between all SystemTap scripts;
so if scripts are loaded for two versions of GLib (for example, a stable
and a development version), those global variables will conflict.

Avoid that by including the soname’s version in the global variable
names.
