Subject: [PATCH] coccinelle: misc: secs_to_jiffies script: Create dummy
 report

When running cocci in report mode, eg:
$make coccicheck M="$dir" MODE=report

It returns this error:
virtual rule report not supported
coccicheck failed
make: *** [Makefile:251: __sub-make] Error 2

Create a dummy rule to avoid this error and run the other cocci scripts.

Fixes: 551dbd1ec7ff ("coccinelle: misc: add secs_to_jiffies script")
