fixes for TJAlien and TJAlienFile in ROOT6
- Update the command to send in TJAlienFile::Open to avoid infinite loop
- Return correct envelope for archive member (to be fixed in server code)
- Change the location of tokencerts to $TMPDIR
- Lock tokencert file to prevent concurrent writes
- Fix: don't request token if connection failed
- Parse two CA locations (path1:path2) from env var $JALIEN_CA_PATH
