to a call to gzip_close() on the tar_outer structure.

pkg_depends: fix unsatisfied dependency installation order

Unsatisfied dependencies are not being installed in the correct order. The
algorithm is not crawling down the dependency chain first when inserting
unsatisfied dependencies, resulting in a correct installation order only for
the first layer of dependencies.

This patch changes the unsatisfied dependency insertion order to first add leaf
dependencies, then move up the chain. The result is a list of unsatisfied
dependencies ordered most-dependent-first.

An example that resulted in the incorrect installation order was:
  A -> B
  A -> C
  B -> D

Without the fix, a most-dependent-first installation order was not guaranteed
more than one layer deep, resulting in an installation order where B is
incorrectly installed before D:
  B, D, C, A
