commit 444750d2e5c6b843b937cbe876ce248e76a2a245

    Handle EROFS/ETXTBSY as permission denied in `fileAccess` (re #8741)
    
    This extends `System.Posix.Files.`access` to map EROFS & ETXTBSY to
    mean permission denied just like EACCESS.
    
    Based on a patch by Alain O'Dea and comments by Duncan Coutts
