sepolicy - move public clatd to private
Clatd is effectively an internal implementation detail of netd.
It exists as a separate daemon only because this gives us a better
security boundary. Netd is it's only launcher (via fork/exec) and
killer.
Generated via:
{ echo; cat public/clatd.te; echo; } >> private/clatd.te
rm -f public/clatd.te
plus a minor edit to put coredomain after clatd type declaration
and required changes to move netd's clatd use out of public into private.
Test: build and install on non-aosp test device, atest, check for selinux clat denials
