selinux: Add missing permissions for ovs-kmod-ctl.
On RHEL 8, a SELinux policy is missing when ovs-kmod-ctl use modprobe
to load kernel modules. This patch adds the missing permissions based
on /var/log/audit/audit.log
Example log of the AVC violations:
type=AVC msg=audit(1599075387.136:65): avc: denied { read } for
pid=1472 comm="modprobe" name="modules.alias.bin" dev="dm-0" ino=586629
scontext=system_u:system_r:openvswitch_load_module_t:s0
tcontext=system_u:object_r:modules_dep_t:s0 tclass=file permissive=0
type=AVC msg=audit(1599085253.148:45): avc: denied { open } for pid=1355
comm="modprobe" path="/usr/lib/modules/4.18.0-193.el8.x86_64/modules.dep.bin"
dev="dm-0" ino=624258 scontext=system_u:system_r:openvswitch_load_module_t:s0
tcontext=unconfined_u:object_r:modules_dep_t:s0 tclass=file permissive=0
