[PATCH v4 1/2] wmic.exe: Support interactive mode and piped commands.

[Louis Lenders]

From: Louis Lenders

See also https://bugs.winehq.org/show_bug.cgi?id=56361

This patch makes piped commands work like for example "echo os get version|wmic" or "type file.txt | wmic" where file.txt contains some commands.
(probably used by program in aforementioned bugreport)

Also support interactive mode (wine wmic.exe)
