varaverk: fix cron format and permissions for dcron

Browse Source 
Unraid's system crond is dcron (dillon's cron daemon 4.5), which reads
/etc/cron.d/ for system crontabs WITHOUT a username field, and refuses
to execute files that are group- or world-writable.

vv_cron_rebuild() was writing "SCHED root bash ..." (with username field)
and leaving the file world-writable (666), so dcron silently ignored every
entry. Fixed:
  - Remove CRON_USER from the generated cron line format
  - chmod 0600 the cron file after writing it
