Update README.md (Fedora Build Dependencies)

[Reith77]

Hey 👋🏾,

This is my first time doing something like this.

I was trying to build picom on Fedora and the meson setup build failed as the xcb-util-devel package was missing.

Updated README.md to include xcb-util-devel package for fedora build dependencies.
