Keep shared arrays WB protected
Sharing an array will cause it to be WB unprotected due to the use
of `RARRAY_PTR`. We don't need to WB unprotect the array because we're
not writing to the buffer of the array.
The following script demonstrates this issue:
```
ary = [1] * 1000
shared = ary[10..20]
puts ObjectSpace.dump(ary)
```
