ci/driver: Remove formatting hack related to COMSPEC command line

It turns out that the extra double quote was required because the "\C"
was surrounded by double quote.

The following syntax works as expected (double quote surrounding the
command and/or args are optional if do not contain spaces):

  cmd.exe /E:ON /V:ON /C ""<command>" "<arg1>" "<arg2>""
