Some minor improvements to the with-vdi script

- return the user command's exit code as the exit code of with-vdi script (unless something else failed in the preparation or post run steps)
- relax the requirement on the user command parameter, both absolute paths and in-paths executables are acceptable
- allow a user command to have its own arguments (i.e. with-vdi vdi-uuid user-command arg1 arg2 ... argn)
