Replace maximize-build-space action

[jayqi]

The easimon/maximize-build-space action is a victim of GitHub changing stuff about how the runners are set up. A lot of the functionality is broken, and this affects us because root-reserve-mb doesn't work anymore.

• GitHub runners changes causes the root reserve argument to be non-functional easimon/maximize-build-space#44
• WARNING: Github runner disk layout is now a fast moving target, breaking this action for many easimon/maximize-build-space#48

This PR replaces the action with some sudo rm -rf commands that just duplicate what the action was doing for the parts where it deletes unwanted software.
