m68k: Avoid VLA use in mangle_kernel_stack()

With gcc 7.3.0:

    arch/m68k/kernel/signal.c: In function ‘mangle_kernel_stack’:
    arch/m68k/kernel/signal.c:654:3: warning: ISO C90 forbids variable length array ‘buf’ [-Wvla]
       unsigned long buf[fsize / 2]; /* yes, twice as much */
       ^~~~~~~~

Replace the variable size by the upper limit, which is 168 bytes.
