[RFC] New package: sagelib-9.5
This is a different approach for a sagemath package than #34030.

Here we build the sagelib as a python module and install it in the system site-packages. The scripts are all installed in `/usr/lib/sagemath/bin` to avoid polluting the PATH. A symlink `/usr/bin/sagelib` is provided.

NOTE: for the moment this is set up so it can coexists together with the `sagemath` package; that's why the package name is `sagelib` (instead of `sagemath`) and the binary is `sagelib` (instead of `sage`). The plan is to rename this package to `sagemath` and the binary to `sage` to replace the other since this one is much simpler and should work better.

With this version jupyter notebook should work out of the box without any adjustments. Please let me know if there's anything missing.

Any comments about packaging, package layout, etc, now is the moment. I would like to get this merged soon since everything seems to be in place.
