[PATCH] Cygwin has trustable filemode

[Mark Levedahl <mlevedahl@gmail.com>]

The supported Cygwin distribution on supported Windows versions provides
complete support for POSIX filemodes, so enable this by default. git as
distributed by the Cygwin project is configured this way.

This fixes one testsuite failure:
t3300 test 17 (diff-index -M -p with mode change quotes funny filename)

Historical notes: Cygwin version 1.7 supports Windows-XP and newer, thus 
dropped support for all OS variants that lack NTFS and/or the full win32 
api, and since late 1.5 development, Cygwin maps POSIX modes to NTFS ACLs 
by default.  Cygwin 1.5 supported OS variants that used FAT as the native 
file system, and had optional methods for providing POSIX file modes on 
top of FAT12/16 and NTFS, though not FAT32.  Also, support for POSIX modes 
on top of FAT were dropped later in 1.5.  Thus, POSIX filemode support 
could not be expected by default on a Cygwin 1.5 installation, but is 
expected by default on a 1.7 installation.

Junio - The above notes are more accurate than in my previous commit message,
so if this commit survives into next/master, I would prefer this version as
opposed to the one now on pu (da875762)
