automake: omit compilation of pyc files on install

* On install, automake calls py-compile, which previously
  compiled python source code to pyc and pyo, which both
  got packaged.
* The python interpreter in OE contains patches to enable
  optimization (pyo) by default:
    04-default-is-optimized.patch
    99-ignore-optimization-flag.patch
* automake created pyc files by calling py_compile.compile()
  and adding the c suffix manually, resulting in identical
  byte code for both pyc and pyo files.
* py-compile-compile-only-optimized-byte-code.patch
  applies to automake 1.11 and automake master, but older
  versions require a slightly modified patch. However,
  older versions are only pinned by chinook-compat and
  nylon, so I left them untouched.
