Test actions/checkout#770

This fix should allow setting safe.directory manually and not having it
overridden by the actions/checkout action.  Test the behaviour works as
expected for both the Cygwin runner (with a manually set safe.directory
in the Git config file) and the Ubuntu runner (with no explicit
safe.directory wrangling).

Disable build steps that are unnecessary / slow / would produce
permanent changes.  Enable steps that we want to check with this action
even though they'd normally only be run for actual releases (subject to
the previous caveat).
