Devel: bump psutil to match Fedora 38 packages

Fedora 38 is the development image used on CI, and one that is popular
for Avocado development at this time.  Let's match the version of
psutil available on the distro with the development requirement.

This avoid the atempt to compile a custom version of psutil.
