[Bug]: perms X not supported in linux_acl module

[darix]

What happened?

X is a valid char in ACLs

For some details see
https://nordisch.org/posts/linux-acl-masks-fun/

I am not sure why we do the whole octal conversion in the first place.

my current attempt to solve it looks like this:

Why do we go through octal here at all?
