Trac #34430: python_igraph: Update to 0.9.11, update spkg-install to use --config-settings

We modernize how we pass build options to the package, using the PEP 517
`--config-settings` mechanism. This is the same as in #34421, where it
was needed as a critical bug fix. (For `python_igraph` there is no bug
because the analysis in #33138 is still true for our current version of
`python_igraph`.)

Also including a minor upgrade to `python_igraph`.
