[PATCH] nfs-utils: getexportent interprets -test-client- as default options

[Ben Myers <bpm@sgi.com>]

With commit 1374c3861abdc66f3a1410e26cc85f86760b51dd Neil added a -test-client-
export to test the exportability of filesystems when exportfs is run.  When
using the old cache controls (i.e. /proc/fs/nfsd is not mounted) exportfs will
read /proc/fs/nfs/exports and find these test client entries.  The dash at the
beginning of -test-client- will be cause getexportent to look for default
options in the rest of the string, which test-client- will not match:

exportfs: /proc/fs/nfs/exports:1: unknown keyword "test-client-(rw"

This patch resolves the problem by testing for -test-client- string in the
check for default arguments.
