Update Gentoo element for element changes

There have been a few changes over the past few months, here we make the
following changes.

* change from backtrack=99 to complete-graph as a more correct flag
* make python version selection more in line with what gentoo supports
* set up python before stuff gets pip installed
* ensure we have the proper pip so we can install pip packages as root
* ensure we have the proper use flags for the disk formatting changes
* set DIB_RELEASE like other distros
* fix openssh-server element for gentoo

* You can set the GENTOO_PORTAGE_CLEANUP environment variable to true (or
anything other than False) to clean up portage from the system and get the
image size smaller.
* Gentoo supports many diferent versions of python, in order to select one
you may use the `GENTOO_PYTHON_TARGETS` environment variable to select
the versions of python you want on your image. The format of this variable
is a string as follows `"python2_7 python3_5"`.
* In addition you can select the primary python version you wish to use (that
which will be called by running the `python` command. The
`GENTOO_PYTHON_ACTIVE_VERSION` is used to set that mapping. The variable
contents can be something like `python3.5`.
