[U-Boot] [PATCH v2] buildman: Create parent directories as necessary

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

When creating build directories also create parents as necessary. This
fixes a failure when building a hierarchical branch (i.e. foo/bar).

Changes in v2:
- only create parent directories for the top build directory to avoid
  sloppy directory creation
