The gc_gens_pos is used to show the status of bucket gen gc.
There is no need to assign write permissions for this attribute.
Here we can use read_attribute helper to define this attribute.
```
[Before]
$ ll internal/gc_gens_pos
-rw-r--r-- 1 root root 4096 Oct 28 15:27 internal/gc_gens_pos
[After]
$ ll internal/gc_gens_pos
-r--r--r-- 1 root root 4096 Oct 28 17:27 internal/gc_gens_pos
```
