dropbear/dropbearkey.service: Allow extra arguments for key generation

Just like the "init" version this script, pass $DROPBEAR_RSAKEY_ARGS to the
'dropbearkey' program when generating a host key.

This allows to speed up SSH connections on read-only root systems by adding
the line DROPBEAR_RSAKEY_ARGS="-s 1024" into /etc/default/dropbear.
