[Crash-utility] [PATCH] x86_64: Add support for new divide_error name

[Nikolay Borisov]

Upstream kernel commit 9d06c4027f21 ("x86/entry: Convert Divide Error to IDTENTRY")
renamed divide_error handler to asm_exc_divide_error. This breaks kaslr
offser derivation when we crash tries to open a qemu image dump. Fix it
by also checking symbols for the presence of the new name.
