build-install-dumb-init: Do not source pokysdk for dumb-init

The buildtools environment is intended for running the poky builds.

It was sourced to provide Python3 to create a virtualenv for building
dumb-init.  However, dumb-init is not related to Poky.  The Python
interpreter and necessary tools should come from the distro.
