archlinux: Rename to arch

The os-release(5) ID on Arch Linux is 'arch', not 'archlinux'.  The
convention of naming the Toolbx images according to the os-release(5) ID
is deeply ingrained in the Toolbx code base.  It will be better to keep
things simple by continuing that practice, instead of adding a one-off
exception.  Especially, now that built-in support for Arch Linux will be
added to Toolbx.
