licensing: add spdx to our .cocci files Since those are chunks of code based on our codebase, it's easiest to use the same license.

coccinelle: make use of SYNTHETIC_ERRNO Ideally, coccinelle would strip unnecessary braces too. But I do not see any option in coccinelle for this, so instead, I edited the patch text using search&replace to remove the braces. Unfortunately this is not fully automatic, in particular it didn't deal well with if-else-if-else blocks and ifdefs, so there is an increased likelikehood be some bugs in such spots. I also removed part of the patch that coccinelle generated for udev, where we returns -1 for failure. This should be fixed independently.

coccinelle: further restrict certain transformations Some transformations generate results we don't want to keep, so let's disable such transformations for specific files. Also, disable const-strlen.cocci everywhere, as the STRLEN macro has a pretty limited scope, so the transformation generates false positives in most cases.
