Clean up building & linking of Process/elf-core.

[brucem]

Summary

• cmake/LLDBDependencies.cmake: elf-core is already included globally in LLDB_USED_LIBS, so it doesn't need to be re-added on individual platforms.

• lib/Makefile: elf-core is linked on each platform, so move it to the global list of used libraries.

• source/Plugins/Makefile: elf-core is built on each platform, so move it to the global list of things to build.
