Corinna Vinschen 971d2dffea Cygwin: get_posix_access: do not merge permissions for just created files 
When creating the POSIX ACL rewrite, the code merging permissions from
everyone/group to group/user ACEs was accidentally called for newly
generated files as well.

This could result in broken permissions, if umask used unusual values
like "0100", granted permissions to everyone/group not granted to
group/user.

Make sure to skip permission merging if the file got just created and
we only want to set correct permissions for the first time.

Fixes: bc444e5aa4 ("Reapply POSIX ACL changes.")
