man/systemd-boot: describe which keys use EFI variables

Some keys have only a transient effect, e.g. 'e', but some have a persistent
effect, e.g. 'd'. This is important informations, but the reader might be
forgiven for not finding that at all obvious when reading the descriptions of
the keys.

Also, mention in loader.conf man page that the settings there might be overriden
by EFI variables. This is another thing that is important but not obvious.
