Add default cmd->cmd_line initialization for liblvm lvm_create().

This needs initialized to non-NULL before using the archive() call.
Normally this is set to the cmdline string when lvm is called from a tool.
We could think about using it in another way, as a potential audit trail
of liblvm calls, or just leave it set to the default "liblvm", similar to
what clvmd does.  For now, just set it to "liblvm".
