selinux: update policy to reflect non-root and dpdk support

The selinux policy that exists in the repository did not specify access to
all of the resources needed for Open vSwitch to properly function with
an enforcing selinux policy.  This update allows Open vSwitch to operate
with selinux set to Enforcing mode, even while running as a non-root user.
