`label.InitLabels` takes options as a string slice in the form of:
user:system_u
role:system_r
type:container_t
level:s0:c4,c5
However, `DupSecOpt` and `DisableSecOpt` were still adding a docker
specifc `label=` in front of every option. That leads to `InitLabels`
not being able to correctly init selinux labels in this scenario for
instance:
label.InitLabels(DupSecOpt([%OPTIONS%]))
if `%OPTIONS` has options prefixed with `label=`, that's going to fail.
Fix this by removing that docker specific `label=` prefix.

Both suffered from different race conditions.
SelinuxEnabled assigned selinuxEnabledChecked before selinuxEnabled.
Thus racing callers could see the wrong selinuxEnabled.
getSelinuxMountPoint assigned selinuxfs to "" before it know the right
value. Thus racing could see "" improperly.
The gate selinuxfs, enabled, and mclist all on the same lock
We need support for read/only mounts in SELinux to allow a bunch of
containers to share the same read/only image. In order to do this
we need a new label which allows container processes to read/execute
all files but not write them.
Existing mount label is either shared write or private write. This
label is shared read/execute.

No substantial code change.
Note that some style errors reported by `golint` are not fixed due to possible compatibility issues.

One of our volume plugins needs to get the label of the target mount point
so that it can set the content inside of the volume to match.
We need label.GetFileLabel() to make this work.
