x86/entry/vdso32: Remove conditional omission of '.cfi_offset eflags'

Now that the minimum supported version of LLVM for building the kernel
has been raised to 17.0.1, the inclusion condition added by

  3e30278e0c71 ("x86/entry/vdso32: Omit '.cfi_offset eflags' for LLVM < 16")

will always be true. Revert the change to clean up the source code.
