kbuild: scripts/genksyms/lex.l: add %option noinput
gcc 4.3 correctly determines that input() is unused and gives the following warning: <-- snip --> ... HOSTCC scripts/genksyms/lex.o scripts/genksyms/lex.c:1487: warning: ‘input’ defined but not used ... <-- snip --> Fix it by adding %option noinput to scripts/genksyms/lex.l and regeneration of scripts/genksyms/lex.c_shipped.
