Four tests had their own copy of "call this until N seconds have passed,
then divide". CallsPerSecond in UnitTest.h does it; each keeps its old
duration and batch size.

UnitTest.h's EXPECT_ macros all call printf and EXPECT_EQ_MEM calls memcmp, but
it included neither <cstdio> nor <cstring> - it has been relying on whatever the
including file happened to pull in first, and TestMpegCsc was the first not to.
The same shape in sceMpegbase.cpp and sceVideocodec.cpp, which use std::min,
std::move and memcpy without saying where they come from.
Also drop an abs() from TestMpegCsc rather than include <cstdlib> for one
subtraction.
