Ensure files and links have missing parent dirs created. Support hard links.

[komish]

This PR addresses two issues:

• When extracting the image tarball to the filesystem, we would fail if a file (e.g. etc/foo.conf) was created before its parent directory (e.g. etc/). This has been fairly uncommon, but for cases where this happens, we'll now create the directory if it's missing.

• We did not handle hard links before, and now we do. We also would fail to handle all links properly, in that links pointing to a path relative to the link would not be resolved properly. This PR properly resolves the link path and the original file's path relative to the link path if it's a relative reference (e.g. ../). All links are still executed using full paths.
