python-packages: Disable parallel build when host pip is needed

This adds PKG_BUILD_PARALLEL:=0 to packages that depend on host Python
packages (HOST_PYTHON3_PACKAGE_BUILD_DEPENDS), because installing
packages with multiple concurrent pip processes can lead to errors or
unexpected results[1].

This also:

* Move HOST_PYTHON3_PACKAGE_BUILD_DEPENDS definitions to before
  python3-package.mk is included

* Update Python folder readme to include PKG_BUILD_PARALLEL:=0
