[tar] Fix support for pipes in Fuchsia

- I broke skipblk() when I added support for lseek(). Seeking does not
work on pipes and it's necessary to fall back to sequential reads.
- Pipes will sometimes return short reads. This is legal but unusual.
I updated unarchive() to cleanly handle this condition.
- Also fixed directory creation, which wasn't setting the mode because
of a premature call to mkdirp().
