[src/trunk]: src/usr.sbin/pkg_install/lib select() -> poll()

[mycroft <mycroft%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/796894df185d
branches:  trunk
changeset: 536592:796894df185d

description:
select() -> poll()

Also, remove a call to path_create() that causes the `prepend' path held by
pkg_perform() to be deleted, causing a core dump later when pkg_perform()
tries to remove it itself.
