    gnu: glibmm-2.64: Fix libsigc++ propagation.
    
    Fixes <https://issues.guix.gnu.org/52519>.  The package was propagating two
    variants of libsigc++.
    
    * gnu/packages/glib.scm (glibmm-2.64)[propagated-inputs]: Replace existing
    libsigc++ package instead of prepending an extra one.
