Change sysattr_list() to only return non-default attributes
Per Mark's suggestion, change sysattr_list() in libcmdutils to only
return non-default attributes.  This appears to fix the problems with cp
-p and mv from ZFS to ZFS and from ZFS to tmpfs, as it no longer tries
to set the other system attributes.

I just changed the logic to remove any attributes from the response list
that had the default values and then return the modified response list
rather than immediately returning the entire response list whenever a
non-default attribute was found.
