fix build

Read access to selinuxfs was neverallowed to app domains in
system/sepolicy commit 14e2e9261fec015ab6fa66f2bc67439f13c45b8d.
However, a dragon app_domain uses device_domain_deprecated.te, which is
triggering the neverallow assertion and breaking the build.

Remove selinuxfs read from device_domain_deprecated to fix the build.

Fixes:

neverallow check failed at
out/target/product/dragon/obj/ETC/sepolicy.recovery_intermediates/plat_policy_nvr.recovery.cil:7880
from system/sepolicy/private/app.te:440
(neverallow base_typeattr_148 selinuxfs (file (ioctl read write create setattr lock relabelfrom append unlink link rename open)))
