[Buildroot] [PATCH 1/2] package/fail2ban: fix data_files installation path

[Angelo Compagnucci <angelo.compagnucci@gmail.com>]

From: Angelo Compagnucci <angelo@amarulasolutions.com>

When packaging data_files in a wheel, those files shall have the destination
path expressed as relative to the wheel installation.
The reason for that is the wheel installation shall be contained inside a
specific folder and/or in site-packages.
When building the wheel file by the bdist_wheel command, python will package
files with absolute pats as python files ending up installing them in
site-packages.

+Subject: [PATCH] setup.py: fix data relative paths
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+As per distutils documentation:
+
+The directory should be a relative path. It is interpreted relative to the
+installation prefix (Python’s sys.prefix for system installations;
+site.USER_BASE for user installations). Distutils allows directory to be an
+absolute installation path, but this is discouraged since it is incompatible
+with the wheel packaging format [1].
+
+When packaging to a bdist_wheel indeed, the files in the "data_files" dictionary
+are not picked at all as data files if they have an absolute path,
+but they are instead added to the wheel as python files.
+This has the effect of installing them as part of python files in the
+site-packages folder when the wheel is installed.
+
+This patch cannot be sent upstream because it breaks the legacy way of
+installing the package with *python setup.py install* and it is needed only to
+comply with the pep517 buildroot compatibility layer.
