scripts: xilinx: always call library.mk on deps

Library dependencies are managed in library.mk, this commit ensures
that library.mk manage and skip them by setting a dummy .TOUCH target.
When building a project, it is desired to rebuild all libraries that
have been modified.
Previously, the solution placed component.xml files as dependencies,
skipping these targets if the file already exists, but ignored changes
to them.
