alloc_debug: get load_bias error
malloc_debug can use libunwind and libunwindstck to unwind backtrace,
if libc.debug.malloc.options contains the string of "backtrace_full",
malloc_debug will use libunwindstck, and if libc.debug.malloc.options
contains the string of "backtrace=*", malloc_debug will use libunwind.
The result of libunwindstck is normal, but the result of libuniwnd
is abnormal, there is a offset between the rel_cp and the correct value,
so addr2line can't decode the right line number.
Libunwind and libunbiwndpack calculate load_bias is different, so malloc_debug
get load_bias alignment with libunwindstack.
