vendor_modprobe loads kernel modules which may create files in
debugfs during module_init().

There is a desire to ensure that modprobe as a service can log to
kmesg to help triage issues, so add support for the -s or --syslog
flag to do so.

Test: use modprobe as a service to load modules, check logs
Change-Id: I884995f364b0fc604861797eb90d7225a372f864
This is needed for libmodprobe to pass module options on the kernel
commandline to kernel modules when they are loaded.

In kernel 4.7, the capability and capability2 classes were split apart
from cap_userns and cap2_userns (see kernel commit
8e4ff6f228e4722cac74db716e308d1da33d744f). Since then, Android cannot be
run in a container with SELinux in enforcing mode.
This change applies the existing capability rules to user namespaces as
well as the root namespace so that Android running in a container
behaves the same on pre- and post-4.7 kernels.
This is essentially:
1. New global_capability_class_set and global_capability2_class_set
that match capability+cap_userns and capability2+cap2_userns,
respectively.
2. s/self:capability/self:global_capability_class_set/g
3. s/self:capability2/self:global_capability2_class_set/g
4. Add cap_userns and cap2_userns to the existing capability_class_set
so that it covers all capabilities. This set was used by several
neverallow and dontaudit rules, and I confirmed that the new
classes are still appropriate.
Test: diff new policy against old and confirm that all new rules add
only cap_userns or cap2_userns;

modprobe domain was allowed to launch vendor toolbox even if its a
coredomain. That violates the treble separation. Fix that by creating a
separate 'vendor_modprobe' domain that init is allowed to transition to
through vendor_toolbox.
