bugon.cocci: fix Options at the macro

The comma after --no-includes makes coccinelle to not run the script:

/usr/bin/spatch -D report --very-quiet --no-show-diff --cocci-file ./scripts/coccinelle/misc/bugon.cocci --no-includes, --include-headers --patch . --dir drivers/media/platform/coda/ -I ./arch/x86/include -I arch/x86/include/generated -I include -I ./arch/x86/include/uapi -I arch/x86/include/generated/uapi -I ./include/uapi -I include/generated/uapi -I ./include/linux/kconfig.h
Usage: spatch.opt --sp-file <SP> <infile> [-o <outfile>] [--iso-file <iso>] [options]
Options are:
  --sp-file                    <file> the semantic patch file
  -o                           <file> the output file
  --in-place                   do the modification on the file directly
  --backup-suffix              suffix to use when making a backup for inplace
...

At least with Fedora 20 coccinelle package:
	coccinelle-1.0.0-0.rc20.1.fc21.x86_64
