tests: prevent regular hangs in ec/nfs.t

When the test systems gets into a memory pressure state (the Jenkins VMs
do not have much RAM), the localhost NFS-mount can get hung. It is
possible to prevent this by writing with O_DIRECT. Unfortnately, the
'dd' command on NetBSD does not seem to support such an option.

The alternative is to reduce the I/O that can get cached on the
NFS-client, like reducing the "count" option for "dd".
