nagios-nrpe: Fix check_nfsserver for buster and bullseye

From buster onward the nfs server doesn't run NFSv4 over UDP (it is out
of spec, see RFC 7530). As such the check broke as it attempt to check
the availability of NFSv4 over UDP.

Right now the check doesn't check for NFSv2 over UDP as it would need to
check if it exist first, as on bullseye it isn't supported by default
anymore.
