Zdenek Kabelac 7ae124743e Use execvp for clvmd restart
Since execve passed only NULL as environ, we had lost all environment vars on
restart - thus actually running  'different' clvmd then the one at start.

Preserving environ allows to restart clvmd with the same settings
(i.e. LD_LIBRARY_PATH)

Add test for second restart.
