ShellPkg: ShellLevel2StripQuotes: Strip consecutive quotes

Browse Source 
When a quotation mark was found, the remaining line would be shifted
in-place to get rid of it. However, the "walker" index would still be
increased and therefore the first character of the shifted part would be
skipped. This means a second quotation mark would not be deleted.
