objtool: Skip unreachable warnings for 'alt' instructions
When a whitelisted function uses one of the ALTERNATIVE macros, it
produces false positive warnings like:
arch/x86/kvm/vmx.o: warning: objtool: .altinstr_replacement+0x0: unreachable instruction
arch/x86/kvm/svm.o: warning: objtool: .altinstr_replacement+0x6e: unreachable instruction
There's no easy way to whitelist alternative instructions, so instead
just skip any 'unreachable' warnings associated with them.
