    Remove setrlimit on FreeBSD
    
    An embeddable interpreter setting a limit that's inherited by spawned child processes is a disaster.. (in fact, the weird limit in Neovim's terminal was what caused me to discover this.)
    
    This code is a relic from the FreeBSD <10 days, and the check for FreeBSD version was not correct (__FreeBSD_kernel__ is defined anyway on newer versions). Let's just get rid of this.
