Title: linux: Enable client NFSv4.1 support by default

I'm only enabling for kernels >= 3.11 to be conservative, because clients and
servers automatically negotiate and use the highest mutually supported version
by default, but only in kernel 3.11 server NFSv4.1 support actually became RFC
compliant.
