Remove duplicate testing simple_server.py

tests/simple_server.py was copied to tuf/scripts/ to "make testing
easier" (cf84d3f), although with
the current test setup the original (and recently patched to fix an
Windows/Py2 test issue) test simple_server.py can be used just as
well.

This commit:
- removes tuf/scripts/simple_server.py
  Note: that version slightly differed from the original test
  server, probably due to demands by the linter that is only executed
  on the tuf core code and not on the tests. However, for the testing
  purposes of simple_server.py these changes (i.e., `SystemRandom()`,
  `if __name__ =='__main__':`) are not necessary.
- updates the tests that used tuf.scripts.simple_server to instead
  use tests.simple_server,
- updates setup.py to not install the simple_server module as
  script, when installing tuf, as it is only a testing script and
  not meant for end-user usage.
