ufw: bump version to 0.36 and add services

This commit brings the version of ufw up to 0.36 since version 0.33
had some problems:
* The setup.py calls sed to replace some variables in the source
code with the correct paths. However, this is done using a hardcoded
path and conflicts with distutils
* The python shebang was not properly corrected in setup.py, leading
to a script that only run if there is a python symlink to python2 or
python3

The first issue is addressed by the bump in version, while the second
one is fixed in patch 0003 of the recipe.

Also, the new version provides examples for systemd service and
sysvinit scripts to autostart ufw. These are added into the recipe
now.

+Subject: [PATCH] setup: only make one reference to env
+
+If sys.executable happens to be '/usr/bin/env python' or something
+similar, the setup script will result in 'ufw' getting /usr/bin/env
+repeated on the top line.  This causes an error at runtime.  Perform a
+quick sanity check on sys.executable before doing the substitution.
+
+While we're at it, change the default value of 'exe' to the one we either
+detected or specified on the build line.

+
+A previous change had modified the way the python shebang was updated to
+follow the same version as the one used to call setup.py. However, it
+used a regex that was not matching anymore. To fix this, the regex
+condition is removed so the shebang line is substituted with the sys.executable
+value. Later in the installation distutils finds the string with the path
+of sys.executable and replaces it with "#! /usr/bin/env python3".
