       upas/nfs: search for stunnele3 in $PATH
       
       Do not hardcode stunnel directory path, just make sure that is installed
       in user '$PATH'. it is required for 'mailfs -t' TLS support, so printout
       an error string if it was not found.
       
       Tested with latest stunnel version 5.17 on OpenBSD and macosx.
       
       % mailfs -t imap.gmail.com ; echo $?
       0
