python3: remove two setup.py cross-compile hacks

Remove two unneeded hacks. The first hack ("setup.py: no host headers
libs" patch) is not needed because we use cross-compiler (e.g.
i586-oe-linux-gcc) which has not been configured with any host system
include or library directories, and thus, we don't get any host system
directories when running "gcc -E -v".

The second hack becomes useless after the first hack has been removed
and we get the standard include and lib directories normally from gcc.

-Patch setup.py so that the detect_modules() function looks for required
-libraries and headers in STAGING_LIBDIR / STAGING_INCDIR.
-
-Without this patch, several extension modules are not built, even though
-their dependencies are present in the compiler's search paths.
-The result is the following warning, and ultimately incomplete packages:
-
-| The necessary bits to build these optional modules were not found:
-| _bz2                  _curses_panel         _dbm

-| nis                   readline              zlib
-| To find the necessary bits, look in setup.py in detect_modules() for the module's name.
