pkg/grub/rootfs.cfg: increase memory limit for /eve and /eve/services…

… cgroups

By special request this patch increases memory limit (soft and hard) for
`/eve` and `/eve/services` cgroups:

  /eve          from 800M to 2048M (dom0_mem configuration parameter)
  /eve/services from 650M to 1600M (eve_mem configuration parameter)

Rised hard limit should help to mitigate OOM caused by bloated zedbox
(pillar) application.
