I'll admit I kinda copy-pasted commit messages around, so that's
probably why the one for this patch sounds a bit hyperbolic :)

Anyway, by the end of the series we'll have to pass dataDir to
testQemuCapsIterate() in addition to using it to build the path for
both the input and output file, so it makes sense to store it into
a variable instead of building it from abs_srcdir plus the directory
name two or more times.

As for why it's stored in the structure, I could easily have used a
global variable instead, but this approach seemed cleaner, especially
considering that we're already using the structure to store data that
is similar in scope (the driver).
