Replaced WPILib.h includes in integration tests with the minimum required subheaders to improve compilation times

Browse Source 
I ran the benchmark in a tmpfs with an Intel Core i5-2430M. I ran it three times for each combination of build invokation and source tree.

First, I tested "make". For master (eb7d55f), I measured an average of 42.751s with a standard deviation of 0.372s. For this commit, I measured an average of 33.394s with a standard deviation of 0.140s. There was a 9.356s, or 22%, improvement with a total error of 1.3%.

Second, I tested "make -j4". For master (eb7d55f), I measured an average of 21.723s with a standard deviation of 0.158s. For this commit, I measured an average of 16.823s with a standard deviation of 0.340s. There was a 4.900s, or 23%, improvement with a total error of 2.7%.
