scripts/oss-fuzz: add a suppression for keymap

When updating to the latest fedora the santizer found more leaks
inside xkbmap:

  FAILED: pc-bios/keymaps/ar
  /builds/stsquad/qemu/build-oss-fuzz/qemu-keymap -f pc-bios/keymaps/ar -l ara
  =================================================================

      #3 0x5631641ca50f in main /builds/stsquad/qemu/build-oss-fuzz/../qemu-keymap.c:215:11

and many more. As we can't do anything about the library add a
suppression to keep the CI going with what its meant to be doing.
