Update direct dependencies to the following versions:

- github.com/shirou/gopsutil/v3 v3.22.4
- golang.org/x/sys v0.0.0-20220520151302-bc2c85ada10a

Otherwise the processes might appear in arbitrary order and
disassociated from their parent process. Also avoid printing a stray
newline after the tree.
