write_logd() is allowed for domain, which means that all domains
are permitted read/write access to /dev. That's overly permissive
and causes substantial differences between user and userdebug/eng
devices.

Remove domain device:dir rw_dir_perms access. It's not needed.

Allow all domains to write/append to logd_debug. logd is responsible
for creating this file if need be. Remove logd_debug file create
permissions. This also eliminates the need for the type_transition
rules.
