Correct Makefile rule for generating custom keymap

When building a custom keymap, after setting GENERATE_KEYMAP := 1 in
drivers/char/Makefile, the kernel build fails like this:

    CC      drivers/char/vt.o
  make[2]: *** No rule to make target `drivers/char/%.map', needed by `drivers/char/defkeymap.c'.  Stop.
  make[1]: *** [drivers/char] Error 2
  make: *** [drivers] Error 2

This was caused by commit af8b128719f5248e542036ea994610a29d0642a6, which
deleted a necessary colon from the Makefile rule that generates the keymap,
since that rule contains both a target and a target-pattern.  The following
patch puts the colon back:
