Instead of each library having an own include directory move the official headers to tools/include instead. This will drop the need to link those headers to tools/include and there is no need any longer to have library-specific include paths when building Xen. While at it remove setting of the unused variable PKG_CONFIG_CFLAGS_LOCAL in libs/*/Makefile.
