libs/project: Complete project_sources_prepare()

The method in which project sources are prepared from either extracted
non-git source archives or sources under $PROJECTS/$project/$SOURCES
are comparable to preparing git sources. This makes knowledge of the
source preparation process mostly transferable across the build
system regardless whether git is involved or not.
