packaging: fix pkg-config files

Notably, this adds the Requires.private required for proper static linkage of
Lix libraries. Some minor missing or duplicated dependencies are also fixed
along the way (although some optional dependencies are omitted due to their
size).

+Previously the pkg-config files distributed with Lix were only suitable for dynamic linkage, causing "undefined reference to…" linker errors when trying to link statically.
+Private dependency information has now been added to make static linkage work as expected without user intervention.
+In addition, relevant static libraries are now prelinked to avoid strange failures due to missing static initializers.
