unwind: unify _LIBUNWIND_ABORT

Rather than use the `__assert_rtn` on libSystem based targets and a local
`assert_rtn` function on others, expand the function definition into a macro
which will perform the writing to stderr and then abort.  This unifies the
definition and behaviour across targets.

Ensure that we flush stderr prior to aborting.
