Although the default and most used way to install MSYS2 is to have it
user-writable, some users prefer to have the root writable only to
admins. In that case, the 01-devices.post script would always print out
two failures on "login" when trying to chmod /dev/{shm,mqueue}. Since
the only supported configuration for MSYS2 is to mount `/` with noacl
where chmod() is a no-op, the failure is purely cosmetic, as is the
chmod invocation itself. For these reasons, let's not chmod at all.
I'm aware the non-user-writable root configuration itself is not
officially supported either, but I've been using it like that for years
now and this is the only issue I know of, so I think it's reasonable to
resolve this.
