Remove system_file:file { lock ioctl } from domain_deprecated. The only
domains triggering this were dex2oat and netd, which are fixed in this
change.
Addresses the following logspam similar to:
avc: granted { lock } for comm="iptables"
path="/system/etc/xtables.lock" dev="sda22" ino=3745
scontext=u:r:netd:s0 tcontext=u:object_r:system_file:s0 tclass=file
avc: granted { lock } for comm="dex2oat"
path="/system/framework/arm/boot-okhttp.art" dev="dm-0" ino=1295
scontext=u:r:dex2oat:s0 tcontext=u:object_r:system_file:s0 tclass=file
Test: device boots and no obvious problems.
