devtools/cocci: make strlcpy replacement smarter

The original coccinelle script worked by replacing instances of
snprintf(.."%s",...) with strlcpy(), but only where the source and dest
parameters were plain identifiers. Allowing expressions for those params
opens up a wide range of other possible changes.
