This cleans up naming of boot loader spec boot entries a bit (i.e. the naming of the .conf snippet files, and the directory in $BOOT where the kernel images and initrds are placed), and isolates it from the actual machine ID concept. Previously there was a sinlge concept for both things, because typically the entries are just named after the machine ID. However one could also use a different identifier, i.e. not a 128bit ID in which cases issues pop up everywhere. For example, the "machine-id" field in the generated snippets would not be a machine ID anymore, and the newly added systemd.machine_id= kernel parameter would possibly get passed invalid data. Hence clean this up: $MACHINE_ID → always a valid 128bit ID. $ENTRY_TOKEN → usually the $MACHINE_ID but can be any other string too. This is used to name the directory to put kernels/initrds in. It's also used for naming the *.conf snippets that implement the Boot Loader Type 1 spec.
