kconfig: scripts/kconfig/zconf.l: add %option noinput
gcc 4.3 correctly determines that input() is unused and gives the
following warning:
<-- snip -->
...
HOSTCC scripts/kconfig/zconf.tab.o
scripts/kconfig/lex.zconf.c:1628: warning: ‘input’ defined but not used
...
<-- snip -->
Fix it by adding %option noinput to scripts/kconfig/zconf.l and
regeneration of scripts/kconfig/lex.zconf.c_shipped.
