  [libunwind][AIX] Fix the wrong traceback from signal handler (#101069)

Patch [llvm#92291](https://github.com/llvm/llvm-project/pull/92291)
causes wrong traceback from a signal handler for AIX because the AIX
unwinder uses the traceback table at the end of each function instead of
FDE/CIE for unwinding. This patch adds a condition to exclude traceback
table based unwinding from the code added by the patch.

(cherry picked from commit d90fa612604b49dfc81c3f42c106fab7401322ec)
