util-linux: Use u-a for getopt

util-linux: Use u-a for getopt

* when enable busybox installs getopt to ${base_bindir} and
  util-linux to ${bindir}, so there is no file conflict, but
  because busybox implementation does not support --long used
  by lsb_release (which RDEPENDS on util-linux) we need to use
  util-linux getopt even when busybox defconfig has it enabled
