How should wake turbulence from aircraft on the ground be avoided during landing?
Wake turbulnce occurs when an aircraft is creating lift.  Since, the airliner is on the ground, there is no wake turbulence.

If you are worried about jet blast from the airliner holding short between the runways, then I would land past the airliner by about 1000 ft.  With the airliners engines at idle, there will be minimal jet blast but if the increase power that jet blast increases significantly.
