objtool: Remove --no-unreachable for noinstr-only vmlinux.o runs

For (!X86_KERNEL_IBT && !LTO_CLANG && NOINSTR_VALIDATION), objtool runs
on both translation units and vmlinux.o. The vmlinux.o run only does
noinstr/noret validation. In that case --no-unreachable has no effect.
Remove it.

Note that for ((X86_KERNEL_IBT || LTO_CLANG) && KCOV), --no-unreachable
still gets set in objtool-args-y by scripts/Makefile.lib.
