Install PKCS#11 module config under /usr/share
    
    This partially reverts a1aff4e992fe6b2d30176800451a6c9b58ae770b so the
    PKCS#11 module configuration is installed under immutable location,
    instead of /etc.
    
    This also makes the spec file future-proof after the upstream changes
    in gnome-keyring and p11-kit:
    https://gitlab.gnome.org/GNOME/gnome-keyring/-/merge_requests/54
    https://github.com/p11-glue/p11-kit/pull/412
