[gnome-keyring/wip/smcv/fix-ci] Stop using volatile in conjunction with atomic operations

[Simon McVittie <smcv src gnome org>]

commit 7e64c48be84e91fd7b464d28f9ee650a332c169d
Author: Simon McVittie <smcv debian org>
Date:   Sun Sep 26 16:41:30 2021 +0100

    Stop using volatile in conjunction with atomic operations
    
    As discussed in <https://gitlab.gnome.org/GNOME/glib/-/issues/600>,
    the volatile qualifier rarely has the semantics that are desired in C/C++.
    With recent gcc versions, combining pointers to volatile-qualified types
    with the __atomic_foo() family of builtins causes compiler warnings.
    
    http://c.isvolatileusefulwiththreads.com/ has some other useful
    references.
