Move zinject from openzfs-zfs-test to openzfs-zfsutils

For Native Debian packaging, zinject binary and man page is
packaged in ZFS test package. zinject is not not directly related
to ZTS and should be packaged with other utilities, like it is
present in zfs_<ver>.rpm/deb packages.

This commit moves zinject binary and man page from openzfs-zfs-test
to openzfs-zfsutils package.
