[perl #114532] Refactor t/op/arith.t to not make TAP by hand

The push and pull tests do that.  In those cases, the TAP creation should 
be centralized.  In those cases, it would be nice to encapsulate the TAP 
creation in one sub, instead of smearing it throughout the file.

In this case, t/op/arith.t, there is a conflict with abs() since test.pl's 
within() uses it, but arith.t's original tryeq_sloppy did too.
