python3: bump to 3.7.0

Other changes include:

 - Refreshing all necessary patches for 3.7.0

 - Add a hash for the license file.

 - Python no longer has it's own internal libffi, as such, host-libffi
   is now required to build host-python3, and is added as a
   dependency.

 - Drop PYTHON3_LIBTOOL_PATCH = NO, since there is no longer any
   internal libffi copy that was causing the libtool patching process
   to fail.

 - A new core module "uuid" is now is added in the Config.in file, and
   relies on util-linux's uuid library.

 - Also, a new patch: 0030-Fix-cross-compiling-the-uuid-module.patch
   is required to fix compiling the uuid module, because the include
   directory search path for uuid.h is hardcoded to /usr/include/uuid,
   which causes an "unsafe for cross-compilation" error during
   compiling if the host pc has uuid headers installed.

 - 0031-Add-an-option-to-disable-uuid-module.patch is added to allow
   disabling the Python3 UUID module, so that when
   BR2_PACKAGE_PYTHON3_UUID is disabled by the UUID library is
   present, the uuid Python module is not built, as expected.

 - 0032-fix-building-on-older-distributions.patch is added to change
   os.replace by os.rename in the update_file.py script to fix
   building on older Linux distributions that have older versions of
   python that don't include os.replace.

   os.rename acts in the same way as os.replace, but is cross-platform
   compatible. Because Buildroot is guaranteed to be built in a POSIX
   environment, it is safe to change replace to rename.

Tested on CentOS6 and Fedora28, All test results passed:
             br-arm-full [1/6]: OK
  br-arm-cortex-a9-glibc [2/6]: OK
   br-arm-cortex-m4-full [3/6]: SKIPPED
