package/suricata: fix shabang for python scripts

/usr/bin/suricatactl and /usr/bin/suricatasc have their interpreter set
to the path of python in the HOST machine.

Use distutils' option '-e' to specify a better shabang.

  - author did not provide their SoB, but it's simple enough to
    not require it for once
  - reword commit log
  - use git-formatted patch, with a proper commit log

+Subject: [PATCH] python: ensure proper shabang on python scripts
+
+When instlling python scripts, distutils would use the python used to
+run setup.py as shabang for the scripts it installs.
+
+However, when cross-compiling, this is most often not correct.
+
+Instead, using '/usr/bin/env python' is guaranteed to find the proper
+python in the PATH, so we need to instruct setyup.py to use that as the
+executable.
