Bug#963520: guitarix: stop using rename.ul in d/rules

Control: retitle 963520 guitarix: depend on prename Sorry, this should have said: Various scripts in src:guitarix, f.e. make_lv2_X11bundle.sh, appear to look for a rename(1) binary. It is likely they find rename.ul from util-linux today. Please make sure they find rename or another tool instead,

Bug#963520: guitarix: stop using rename.ul in d/rules

Source: guitarix Version: 0.39.0+dfsg1-3.1 Dear Maintainer, your package appears to use `rename.ul` from util-linux, which will stop installing this binary soon. Please use `rename` from prename or other tools instead. Thanks, Chris
