gpu-compute: call createThreads() on cpu objs in apu_se.py

commit 8ad26e2688b8736f9290086bb4026cc7500429e9
cpu: Don't override ISA if provided by user

removed the default ISA from the BaseCPU, and instead relies on
createThreads() to initiate a default ISA if none is specified. the apu_se.py
script, however does not call creatThreads() leading to a fatal when
constructing CPU objects. this patch adds the appropriate calls to
createThreads() inside apu_se.py.
