github: run actions with secrets only in seL4 org

Some of the Github actions in this repository require secrets for
access to hardware test or other compute infrastructure, or for
deployment. When these are run in a fork on GitHub they are safe,
but generate annoying error messages.

This commit adds tests in the relevant actions whether they are run
from the seL4 org or not, and skips the action when they are run
outside. This should make the remaining actions more useful on forks.
