[Patch] Allow to disable root privileges with CYGWIN=noroot

For members of administrator group, Cygwin runs with root access rights. 
Cygwin enables the Windows backup and restore privileges which are not 
enabled by default.

This is IMO not desirable under all circumstances.

This patch adds a new flag to the Cygwin environment variable.
If 'CYGWIN=noroot' is set, the extra privileges are removed after Cygwin 

This allows to run a Cygwin shell with the same default access rights as 
cmd or explorer.


$ cd /cygdrive/c

$ ls -l 'System Volume Information'
----rwx---  1 root SYSTEM   0 Feb 22  2009 MountPointManagerRemoteDatabase

$ CYGWIN=noroot ls -l 'System Volume Information'
ls: cannot open directory System Volume Information: Permission denied

I'm sure there is something missing, so no changelog for now :-)
