dhcpcd: ignore MTU Smaller than 577.

Normally 576 is the smallest valid mtu but some cable provider set this
also if they support much higher mtu's. Fedora does not accept
this to prevent speed problems with such isp connections so we do the same.
If you really need mtu=576 you can still force at at the setup.
