    sstate.bbclass: check if mirror directory is writable
    
    Commit 51edde653707e7a3cd2186082458f01f32cd1996 makes a wrong assumption
    that SSTATE_MIRRORS have write permissions.
    
    A mirror is by definition outside of it's user control. In my use case
    it happens I does not have permissions to update the access time of the
    dereferenced symbolic-link file.
    
    Checked if file is writable before changing its atime.
    
    Thanks to Paulo Neves for the patch.
