math/big: don't require runtime.(*Frame).Next symbol present

I don't know why the test requires runtime.(*Frame).Next symbol
present in the binary under test. I assume it is just some
sanity check? With CL 268479 runtime.(*Frame).Next can be pruned
by the linker. Replace it with runtime.main which should always
be present.

May fix the longtest builders.
