Most of /data/data/ is invisible

[Nemris]

Describe the bug
When using the Explorer, there are only two directories visible inside /data/data/: com.google.android.gms and eu.thedarken.sdm.
This extends to custom SystemCleaner filters that operate on apps' private data, making them unusable.

To Reproduce
Steps to reproduce the behavior:

1. Open Explorer from the side bar.
2. Move to /data/data/.
3. Observe that apps' private data is not shown, save for GMS and SDM.

Expected behavior
The apps' private data should be visible inside /data/data/, as they are under other root-capable file managers.
Additionally, custom SystemCleaner filters that operate on apps' private data should work, provided their logic is sound.

On Android 11+ the content of /data/data is filtered for security/privacy, the actual content can be found under /data_mirror, but you are right, with the SystemCleaner filters it can be annoying, I'll look into a workaround.

I can confirm that both /data_mirror/data_ce/null/0/ and /data_mirror/data_de/null/0/ appear to show app data, yes.

The interesting question is - why do apps such as (the closed-source) Total Commander and (the open-source) Termux appear to show /data/data/ just fine with root privileges? Maybe it'll be useful for your workaround.
