Subject: [PATCH] rpi: remove custom environment changes

The changes applied here deviate from the Raspbian environment and
will change behaviour. These are not necessary for the Mender
integration to work and are mostly for "convenience" and for this
reason we drop them to stay as close to possible to the Raspbian
environment.

Changelog: None
