Installing custom certificates has no effect on android

While the installation of the certificate works and the certificate file is present in system/etc/security/cacerts it shows no effect and is not trusted. This means that without the certificate pinning bypass, no traffic can be collected.

The problem seems to be connected to the file permissions. httptoolkit, where we found the tempfs workaround we are currently using, updates the file permissions and SELinux permissions of the cert folder.
When checking the permissions of our certificate, I noticed that we don’t even set any of the file permissions correctly:

-rw-rw---- 1 u0_a148 media_rw 1172 2023-03-28 15:05 c8750f0d.0

My guess this is a regression from #94, because before we pushed the file as root instead of via su -c, which should have at least set the owner correctly.
