File fix-python-lib.patch of Package pgadmin4

From: Antonio Larrosa <alarrosa@suse.com>
Subject: Fix a linking to the python library

Python 3.8's python3-config doesn't seem to include the python3.8 library anymore, so
we have to add it ourselves. Use an environment variable (just as in the Windows case)
to find out the library version to link to.
