PR20307: fix references to private global in tapset

Previous code could not resolve a reference to a private global
(defined in a tapset) within a probe alias (from that same tapset).
We now try matching up the mangled name in addition to the plain one
in symresolution_info::find_var() when searching the
session.library_files[].globals.
