Sentry Crash Report:

Description Gabriel Cavallo 2016-10-16 10:53:11 UTC 
The Ark "Extract" ServiceMenu is grayed as unusable on archives that don't have write permissions.
Extraction should require write access to parent folder but only read access to the archive itself.

Reproducible: Always

Steps to Reproduce:
Make archive read-only `chmod 440 example.zip`.

Actual Results:  
Right click archive in Dolphin and the "Extract" menu is unusable.

Expected Results:  
Read permission on archive should allow extraction.

Allow extraction of read-only archives

Currently we use `KFileItemListProperties::supportsWriting()` to check whether a folder
is read-write and can be used as extract destination, but this function returns
false if the archive is read-only. A read-only archive can still be extracted,
so we need to implement our own check for the writability of parent folders.
