msvcrt-A09: _close bugfix

[Jaco Greeff <jaco@puxedo.org>]

This patch in the msvcrt-A?? series fixes a bug in the _close 
implementation in that a close on a dupped file descriptor from 
STDIN/STDOUT/STDERR might try and free the non-dynamic MSVCRT_FILE* 
structure assigned to the original STDIN/STDOUT/STDERR file descriptor.

Changelog:
* dlls/msvcrt/file.c: Jaco Greeff <jaco@puxedo.org>
- Make sure that the _close of _dup'ed file descriptors desn't try to 
free the MSVCRT_FILE structures associated with STDIN/STDOUT/STDERR
