Install sage-env-config as part of sage_conf

[mkoeppe]

As a follow-up to #21559 and #30128, we reassign sage-env-config from the package sagelib to the package sage_conf.

(After #22731, sage-env-config is no longer required by the sage script.)

(This is preparation for allowing installation of sagelib for example in a conda environment without having to run ./configure first - see #28745, #30845.)

Part of Meta-ticket #21707: Split sage-env into 5 to clean up sage configuration

[mkoeppe]

Branch on this ticket does NOT work because pip/setuptools do not handle the symlink well.

Perhaps it's easier to get rid of sage-env-config altogether (#29852).

Using flit instead of setuptools (#29854) does not help for this ticket because flit does not know how to install prepared shell scripts -- it can only install Python scripts

It would probably suffice to just replace the use of pip by setup.py install.

Thanks!

[mkoeppe]

I set it to "needs info" because this design potentially conflicts with #30896 (./configure --without-python); see also #29852 (Get rid of sage-env-config).

Still needs review...

OK.
