  t/test.pl - assign caller() to separate vars in _where()

_where() is a heavily used, small subroutine within test.pl. It currently
assigns all eleven of caller()'s return values to array elements, then
uses only the second and third of these to construct a return string.

This commit changes the assignment to use separate variables, which ends
up being more efficient.

Benchmarking suggests that _where() is about 30% faster as a result.
The overhead of ok( ... ) calls is reduced by about 10%.
