    sh: Fix bss-based buffer overflow in . builtin.
    
    If the length of a directory in PATH together with the given filename
    exceeded FILENAME_MAX (which may happen even for pathnames that work), a
    static buffer was overflown.
    
    The static buffer is unnecessary, we can use the stalloc() stack.
