ueventd is allowed to change files and directories in /sys,
but not symbolic links. This is, at a minimum, causing the
following denial:

type=1400 audit(0.0:5): avc: denied { getattr } for comm="ueventd" path="/sys/devices/tegradc.0/driver" dev=sysfs ino=3386 scontext=u:r:ueventd:s0 tcontext=u:object_r:sysfs_devices_tegradc:s0 tclass=lnk_file

Allow ueventd to modify labeling / attributes of symlinks.

We had disabled the neverallow rule when system_server was

back.

Many of the neverallow rules have -unconfineddomain. This was
intended to allow us to support permissive_or_unconfined(), and
ensure that all domains were enforcing at least a minimal set of
rules.

Now that all the app domains are in enforcing / confined, there's
no need to allow for these exceptions. Remove them.

Chrome renderer processes dlopen() a shared library from
gmscore. Open and read on app data file is already allowed,
but execute isn't, so the dlopen() fails. This is a regression
from K, where the dlopen succeeded.

Longer term, there's questions about whether this is appropriate
behavior for an isolated app. For now, allow the behavior.
See the discussion in b/15902433 for details.
