[PATCH v2 1/5] Documentation/kcov: Include types.h in the example.

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

The first example code has includes at the top, the following two
example share that part. The last example (remote coverage collection)
requires the linux/types.h header file due its __aligned_u64 usage.

Add the linux/types.h to the top most example and a comment that the
header files from above are required as it is done in the second
example.
