[ITA] libsigc3.0

[Philippe Baril Lecavalier]

libsigc3.0 3.0.3 (2020) -> 3.6.0 (2023)

Similar business to libsigc2.0, another parallel-installable ABI. Same 
issue with Doxygen but we have established a decent workaround. I 
thought I tested and sorted it out a while ago, turned out I missed a 
subtle difference in docs path vs 2.0, hence hanging build with scallywag.
