[PATCH perl@17014] t/op/arith.t -- don't test infinity if itdoesn't exist

For VMS, all VAX builds and any configurations on Alpha that have not taken 
the default IEEE floating point format will not have its infinity/NaN 
features.  The patch below make arith.t aware of that.  Similar problems 
exist in pack.t but I have not yet addressed those.
