tst_BenchlibCallgrind: fix x86 preprocessor check

Browse Source 
Its twoHundredMillionInstructions() test has #if-ery to limit it to
gcc and x86; however, it was testing only __i386 for the x86 part,
where gcc defines __x86_64 instead on modern 64-bit systems. In the
process, invert the condition and the branches it controls - positive
tests are easier to comprehend.
