rS355374: Pass 0 to __builtin_frame_address() to appease modern GCC.

Summary

Modern versions of GCC warn about passing non-zero values to
__builtin_frame_address(). Passing 1 is a cosmetic change to
remove the db_trace_self() frame from the printed stack trace.

Test Plan

lets sparc64 GENERIC build with GCC 6.x.
compile tested only, not run tested
