History
Yifan Hong 5d89abde99 Allow to getattr kmsg_device 
These denials occur on boot when android_get_control_file also
changes from readlink() to realpath(), because realpath() will
lstat() the given path.

Some other domains (fastbootd, update_engine, etc.) also uses
libcutils to write to kernel log, where android_get_control_file()
is invoked, hence getattr is added to them as well.
