[SETUP:REACTOS][SYSSETUP] Fix Shift-F10 cmd.exe invocation.

Browse source 
Pressing Shift-F10 to open cmd.exe when the setup program runs from
a different current directory than System32, now works correctly.

Use the 2nd CreateProcessW() `lpCommandLine` parameter, instead of the
1st parameter `lpApplicationName`, so as to use default path search.
The command-line buffer given to the 2nd-parameter can be temporarily
modified by CreateProcessW(), thus use an on-stack buffer.
