gdb: make gcore-1.in and gstack-1.in shellcheck-clean

Fix all the warnings pasted below, mostly by accepting shellcheck's
suggestions.

The only exception is $GDBARGS in gstack.  There, we actually want the
space-splitting, I suppose, so I chose to just ignore the warning on
that line.  In any case, I'm not looking to change the existing behavior
in this patch.

The warnings:

    $ shellcheck gstack-1.in gcore-1.in

    In gstack-1.in line 135:
    "$GDB" --quiet -nx $GDBARGS <<EOF |
                       ^------^ SC2086 (info): Double quote to prevent globbing and word splitting.

    Did you mean:
    "$GDB" --quiet -nx "$GDBARGS" <<EOF |

    In gcore-1.in line 130:

    binary_path=$(dirname "$0")

            ^-------------^ SC2268 (style): Avoid x-prefix in comparisons as it no longer serves a purpose.
