upgrade: fix output when no packages to upgrade.

When upgrading, if the only package to upgrade is a
pinned package, the output looked like that:
	==> Upgrading 0 packages, with result:

	==> Not upgrading 1 pinned package:
	<<package_name & version>>

The blank line is not beautiful. This commit fixes
the output and replaces with:
	==> No packages to upgrade
	==> Not upgrading 1 pinned package:
	<<package_name & version>>

Closes #26157.
