Commit 7688161 "hal_*_(client|server) => hal(client|server)domain"
added neverallow rules on hal_*_client attributes while simultaneously
expanding these attribute which causes them to fail CTS neverallow
tests. Remove these neverallow rules as they do not impose specific
security properties that we want to enforce.
Modify Other neverallow failures which were imposed on hal_foo
attributes and should have been enforced on hal_foo_server attributes
instead.
Bug: 69566734
Test: cts-tradefed run cts -m CtsSecurityHostTestCases -t \
android.cts.security.SELinuxNeverallowRulesTest
CtsSecurityHostTestCases completed in 7s. 627 passed, 1 failed
remaining failure appears to be caused by b/68133473
Test: build taimen-user/userdebug
