include man in ucore and ucore-hci images

[johnmmcgee]

What: Include the man package in the ucore and ucore-hci images.

Why: The ability to have offline access to documentation is not only a "nice to have" but at times an essential item when configuring a system that may not have network access available at the given time.

Solution: add 'man' to the package list.

I did some testing on this... apparently, some RPMs don't install the man pages if man itself isn't installed first?

Example: one can install man-db and then notice that tnere are no man pages for bash. Despite them being listed in rpm -ql bash. This differs from silverblue.

I suspect it has something to do with the original image composition.
