Always set something for RELEASE_NAME

- Move the setting of RELEASE_NAME outside of the check for whether or
not we're on Jenkins.
- Without having RELEASE_NAME set to something, Excelsior's fetching of
bootloader debs fails (and that's now required on external builds, as LK
source is not public).
