cppcheck: Use inline suppression for ffsl()

We define our own ffsl() as a weak symbol, in case our C library doesn't
include it.  On glibc systems which *do* include it, this causes a cppcheck
warning because unsurprisingly our version doesn't pick the same argument
names.  Convert the suppression for this into an inline suppression.
