Remove set_fs_pwd() configure check

Browse Source 
This function has never been exported by any mainline and was only
briefly available under RHEL5.  Therefore this check is being removed
and the code update to always use the wrapper function.

The next step will be to eliminate all this code.  If ZFS were updated
not to assume that it's pwd was / there would be no need for this.
