compiler: fix trac issue #9817 

Summary:
When we call runHandlers, we must pass it a ForeignPtr. To ensure that
this happens, we introduce a wrapper that receives a plain Ptr and
converts it into a ForeignPtr. Then we adjust startSignalHandlers in
rts/posix/Signals.c to call the wrapper instead of calling runHandlers
directly.
