4.1 client: tame debugging spam

As of 6439a2f11cbc "4.1 server: add -v flag & silence random output"
server tests were producing huge logs.  Fix.

(Better might be to remove the --showtraffic option from 4.0 and 4.1 and
just rely on --verbose instead?)

4.1 server tests: don't require large-ACL support

Some servers or filesystems aren't going to support ACLs with hundreds
of entries, and that's OK, we shouldn't be erroring out because they
don't.

Better would be to test a range of sizes and allow either OK or (past a
certain point) an appropriate error (FBIG?).

Ideal might be to actually allow pynfs to support server limits such as
this without reporting them as errors.

4.0 server tests: allow NOENT on empty symlink creation

As far as I can tell NFS4ERR_NOENT is also a legal return here.

Open files with OPEN4_SHARE_DENY_NONE for DELEG5 test

DELEG5 test, while getting the READ delegation, uses
OPEN4_SHARE_DENY_WRITE as that is the default. Pass
OPEN4_SHARE_DENY_NONE explicitly as that is assumed
in the test.
