simplify updating python versions in gentoo

Browse Source 
portage now generates /etc/python-exec/python-exec.conf based on the
order of PYTHON_TARGETS in /etc/portage/make.conf

fixes an issue where ARCH was being detected as amd64 not x86_64
fixes kernel installs (virtual/dist-kernel)

standardizes simple if statements (note, the 'shorthand' method will
pass the exit code back to shell but the 'longhand' does not).

`GENTOO_PYTHON_ACTIVE_VERSION` is used to set that mapping. The variable
contents can be something like `python3.6`.
* You can enable overlays using the `GENTOO_OVERLAYS` variable. In it you
should put a space separated list of overlays. The overlays must be in the
official overlay list and must be git based.
