build(clint): remove "function size is too large" warning

This warning is essentially only triggered for ported vim functions.
It's unlikely that we'll refactor vim functions solely based on their
size since it'd mean we'd greatly deviate from vim, which is a high cost
when it comes to importing the vim patches. Thus, this warning only
serves as an annoyance and should be removed.
