allow to pass commands to mssqlclient.py via command line

allow to pass commands to mssqlclient.py via the command line directly instead of only using a input file

Hi @trietend,

Just a tiny change to align the new parameter with similar ones in other examples, like:

• impacket/examples/goldenPac.py

  Lines 1083 to 1085 in af51dfd

  	parser.add_argument('command', nargs='*', default=' ',
  	help='command (or arguments if -c is used) to execute at the target (w/o path). Defaults to '
  	'cmd.exe. \'None\' will not execute PSEXEC (handy if you just want to save the ticket)')

• impacket/examples/wmiexec.py

  Lines 384 to 385 in af51dfd

  	parser.add_argument('command', nargs='*', default=' ', help='command to execute at the target. If empty it will '
  	'launch a semi-interactive shell')

Thanks!
