Change DPMS code to accommodate enforce states on boot.

We need to respect if setenforce (selinux enforce), setsebool (booleans),
or setprop (mmac enforce) are set in the any of the init.rc files.
This set of changes will allow the init.rc values to win over any
potential device admin wishes.

inside PMS.

Bring install-time code inline with AOSP.

Recent submissions to AOSP rework some of the
internal logic of SELinuxMMAC and the PMS.
Bring our maintained version inline with
those changes while still allowing policy
to dictate all seinfo values regardless
of location.

Save off the seinfo value with packages.list.

Patch adds the seinfo label per package to the file.
This is of particular interest to the run-as program
which uses the seinfo tag to correctly label the
app security context before running the shell.

Allow device admin policy to override policy boolean state.

Prior code only allowed a false to true transition for a device
admin policy. This was to ensure that a default true was always
upheld. Reverse this and allow a device admin policy to take over
the setting of all booleans; even those set by the init.rc.
