Disable loop restoration at speed 5

Started an encoder speed 5, aiming at really fast AV1 encoding.

Borg test result:
                         avg_psnr:   ovr_psnr:   ssim:  avg speedup:
objective-1-fast(fixed-q): 0.877       0.889     1.015    16.8%
midres(vbr):               0.730       0.735     0.758    10.9%
hdres(vbr):                1.120       1.135     1.302     8.2%
