project-xilinx: Update the generic dependency list

[AndreiGrozav]

The generic project dependency list contains:
system_top*.v
system_bd.tcl
system_project.tcl
system_constr.xdc
This items will not be included in the auto generated makefiles. But used as generic dependency.

This PR adds:
-wildcard check of system_constr*.xdc.
-wildcard check of system_constr*.tcl.

This wildcards are needed for designs that ,for example, contain files like system_top_lvds.v
