[Ada] Fix __gnat_backtrace for VxWorks7 on x86
A STORAGE ERROR is raised in __gnat_backtrace:
adainit: 0x00400DBC
Execution of ce.vxe terminated by unhandled exception
raised STORAGE_ERROR : SIGSEGV: possible stack overflow
Call stack traceback locations:
0x4082f1 0x408323 0x4080c9
It was passing with vxsim because the WRS_RTP_BASE is set to a different
place hence the (CURRENT) < (TOP_STACK) was stopping the backtrace at the
right time. So let's stop at the main symbol when RTS=rtp.

* tracebak.c (STOP_FRAME): Harden condition.
(is_return_from, EXTRA_STOP_CONDITION): New helpers for VxWorks in RTP
mode.
