util/bash-completion: Disable SC2120 shellcheck warning

SC2120 (warning): function references arguments, but none are ever passed.

In grub-completion.bash.in line 63:
__grub_get_options_from_help () {
^-- SC2120 (warning)
     local prog

     if [ $# -ge 1 ]; then
         prog="$1"

The arg of __grub_get_options_from_help() is optional. So, the current
code meets the exception and does not need to be modified. Ignoring the
warning then.
