This patch reverts changes made to `os.makedirs()` in Python 3.7.

Prior to Python 3.7, mode argument also affected newly-created
intermediate-level directories, and that is not the case anymore [1]. The
reason was that with mode preventing directory creating, the function fails
after it creates the first intermediate-level directory.

Since there is Solaris code that depends on the old behavior, this patch brings
it back. Note that we are not the only ones affected by this; upstream is
already considering reverting this change [2].
