Fix python module build method

[dchassin]

This PR fixes issue #986.

Current issues

1. The wheel name does not conform to PEP 440 standard.
2. This PR to the build method doesn't make the deprecation error go away. However, it does bring the build method up to PEP 440 standards, which is important.

Code changes

• Fix gldcore/link/python/{Makefile.mk,setup.py} to use python build module instead of disttools.

Documentation changes

None

Test and Validation Notes

You may notice warning errors about the version name not conforming to the PEP 440 standard. This is not a problem. Yet.

Makefile.mk contains line @python3 -m pip uninstall gridlabd -y which breaks make reconfigure on Darwin

Found existing installation: gridlabd 4.2.30.220112
ERROR: Cannot uninstall 'gridlabd'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

This error will only occur if you use make reconfigure or make clean on an build made with the older python build method. Use . utilities/cleanwc followed by autoreconf -isf && ./configure instead to avoid this transient problem. A message to that effect has been added to the makefile when that error occurs.
