runtime: skip testSetPanicOnFault for gollvm

LLVM doesn't support non-call exception. This test was passing
more or less by luck: if the faulting instruction is between two
calls with the same landing pad (in instruction layout order,
not the program's logic order), it generates a merged PC range
that covers the faulting instruction. If the instruction layout
order changes, or it uses two different (but may be degenerate)
landing pads, this doesn't work.
