systemd-boot-cfg: add .conf suffix to default entry label

Since systemd v245 (commit 6cd12ebcfe459466257ea63022a32515d756e719), systemd-boot
expects default entry to have the complete filename as value.

LABELS from poky are by default without any suffixes like "boot install", so default entry
does not have the .conf suffix as well and systemd-boot is not able to use this information
and it's starting in any case the first entry. To be able to start another entry by default,
.conf suffix is required.

With this change, LABELS variable can still be used by other bootloaders and being used as description
field.
