rtc: Increase thresh to select sb-size=64 for MT

Use slightly higher threshold so the 3 remaining
high resolution clips in rtc_screen: (buganizer.1900_1306,
colorslides.1820_1320, crd_colwinscroll.1920_1128)
will also select sb-size=4 (for 4 threads with 4 tiles).

This gives ~7-10% speedup in encoder-fps for 4 threads
(with 2x2 or 4x1 config) for these clips.
