Subject: [PATCH -next] objtool: use arch_jump_destination in read_intra_function_calls

arch_jump_destination() is used instead of offset + len + immediate
for jump destination.
But in read_intra_function_calls it didn't get changed.
It can make trouble for other arches development such as arm or ppc.
Fix it.
