Fix support for multiarch distributions using lib_suffix

Merged Andoni Morales Alastruey requested to merge ylatuya/cerbero:libdir into main

The lib_suffix configuration variable was initially created to support multiarch distros,such as Fedora using lib64 instead of lib for x86_64 builds. This MR addresses all the cases in which 'lib' is hardcoded. It also create a new replacement for file listing named libdir and fixes all recipes files listing hardcoding 'lib'
