The location of the Airskiff site recently changed [0], causing the
Airskiff job to fail. This change updates the "reduce site" playbook to
match the job in treasuremap, thereby avoiding the directory which no
longer exists.
The change also removes the usage of install-packages script, because
it was removed [1].
