[gjs/april-maintenance: 1/3] CI: Update some Valgrind suppression expressions

[Philip Chimento <pchimento src gnome org>]

commit 18c48ea24b9b8c68758ef92bf698d45ae98bb38f
Author: Philip Chimento <philip chimento gmail com>

    CI: Update some Valgrind suppression expressions
    
    To account for changes in mozjs68, and different call stacks of the same
    leak in different versions of software.
    
    Some suppressions are no longer necessary.
    
    We also have to tell valgrind not to trace /usr/bin/stat since we use it
    in a script test.
