    wslua: fix wslua file test failure
    
    Lua 5.2.4 built with -DLUA_USE_APICHECK detected a stack issue:
    
        tshark: lapi.c:175: lua_settop: Assertion `(-(idx+1) <= (L->top - (func + 1))) && "invalid new top"' failed.
    
    Function File_read always assumes that File_read_line pushes a value on
    the stack (which clearly did not happen). On read failure, it would then
    pop the stack (tripping the assertion) to push nil.
    
    The other user (File_lines) is also affected by this change, but the Lua
    5.2.4 documentation says that it should also return nil on EOF, fitting
    this implementation.
