libpayload: Fix variable shadowing in PDCurses

PDCurses has a function called overlay() and also uses
    overlay as a variable name in some functions.

This patch fixes the ambiguity that caused warnings like
    curses/PDCurses-3.4/pdcurses/overlay.c: In function '_copy_win':
    curses/PDCurses-3.4/pdcurses/overlay.c:51:39: warning: declaration of 'overlay' shadows a global declaration [-Wshadow]
    In file included from curses/PDCurses-3.4/curspriv.h:16:0,
                     from curses/PDCurses-3.4/pdcurses/overlay.c:3:
    curses/PDCurses-3.4/curses.h:1014:9: warning: shadowed declaration is here [-Wshadow]
