  redhat: fix upgrades where group doesn't exist

The upgrade from older Open vSwitch versions on RHEL will try, as much as
possible, to preserve the system.  This means no new users or groups are
created.  As an effect, it's possible for the chown to fail, because the
hugetlbfs group may not exist.  While it did on my systems, it was not
there on others.

This change allows the ExecStartPre commands to fail.  In the case that the
user doesn't use DPDK, it won't matter anyway.

Fixes: e3e738a3d058 ('redhat: allow dpdk to also run as non-root user')
