fix(ipxe): fix filename checks

The `filename` contains the full path to the file, usually the netboot
assets are in `/` of a tftp server, so the check if its booted from the
ipxe assets will always fail. Add an additional check prepended with `/`
to allow the check to pass when booted from the root of a tftp server.

Also add loading of MAC- ipxe scripts with hypens in addition to raw, i.e.
`MAC-00-11-22-33-44-55.ipxe` or `MAC-001122334455.ipxe`.

Fixes: #1097

+- Loading of tftpmenu local-vars.ipxe, HOSTANEM-${hostname}.ipxe,
+  MAC-${mac:hexraw}.ipxe, MAC-${mac:hexhyp}.ipxe and custom menu.ipxe from the
+  root of the tftp server. The root `tftp-root-path` is a variable and can be
+  set in `local-vars.ipxe` to override. The default is `/`.
