rbutil: Fix bootloader installation for various players.

Reworking handling of player specific data (static player configuration,
as well as information retrieved from the server) changed the behaviour
on a non-present configuration entry. This eventually caused the
mountpoint not being set for players that don't have a bootloader file
on disk. Fixing this accidentially removed the default-if-not-found
handling for the bootloader file.

Restore the old default value behaviour for both cases.
