vp9_active_[hv]_edge: add missing vpx_clear_system_state

this fixes runtime errors with clang -fsanitize=integer in x86 builds:

../vp9/encoder/vp9_rdopt.c:3250:17: runtime error: signed integer
  overflow: 18 - -2147483648 cannot be represented in type 'int'
../vp9/encoder/vp9_rdopt.c:3277:16: runtime error: signed integer
  overflow: 26 - -2147483648 cannot be represented in type 'int'
