[symbolize] Handle backtrace addresses correctly

This change handles the issue where the reported addresses are return addresses
and not the caller address. Because subtracting 1 will on x86_64 and AArch64
cause the address to be in the middle (or start on x86_64 in rare cases) this
is always a valid technique.

Test: Just symbolized a real crash with it
