Add dependency information to output of "pkg describe" (patch #9880).

* describe.m: Add new field "depends" to pkg_desc_list structure.
Call print_package_description() with additional input pkg_desc_list.depends.
* describe.m (print_package_description): Change function prototype to
accept new input with dependency information.  Format and print output
on dependencies.
