bignum overrides.t: Fix for 5.8

We use the ;$ prototype for testing global overrides under 5.8, as it
had no _ prototype.  But back then (before 5.14, in fact) ;$ did not
give a function unary precedence.

Comparing against 5.009004 in bigint scope is the same as comparing
against 5, resulting in incorrect version checks and skips being
skipped.
