python3: bump to version 3.6.4

Re-worked patch `003-do-not-run-distutils-tests.patch`
to reduce patch-size.

Removed `011-fix-ncursesw-definition-colisions.patch`
it is fixed upstream.

Refreshed with `make package/python3/refresh`

Resetting PKG_RELEASE to 1.
This variable was never used for pip3 & setuptools, since
VERSION is specified in the package definitions.
