gnulib-tool.py: Optimize directory creation.

[Collin Funk]

Hi Bruno,

Separating this from the other thread so it is easier to follow.

This patch handles the directory creation upfront instead of checking
for every single file, as you mentioned earlier [1].

The previously unused variable was slightly incorrect. We have to join
the directory name with self.testdir. I ran it without this and the
directories were made in the current working directory, causing the
tests to crash.
