Mahmoud Al-Qudsi 2157d91a5c Re-add explicit littlecheck HOME/XDG_CONFIG_HOME overrides on request
This was requested by a team member who would like for some tests to
remain invokable (in thier own $HOME) directly via littlecheck without
relying on the test driver to prep the environment.

A comment explaining the rationale is also added so this doesn't get
passed down as folklore "you need to include this for tests to run" even
though no one understands why.
