dtrace: ensure that PID 0 has a psinfo struct

Test builtinvar/tst.psinfo.d lists a large amount of memory access
errors trying to read from non-existant psinfo information for PID 0.
This commit enusres that prior to dtrace doing any work, PID 0 (the
init_task) has a psinfo structure associated with it.
