gtk-update-icon-cache is in the "bin" output of GTK+. For example:

------
$ guix build gtk+
/gnu/store/0mskf7mzfrhrnkixfadrvvr5lgfssfzf-gtk+-3.24.0-bin
/gnu/store/iypmqb5a6g1f1xw4s7m88vy51hgyh0p1-gtk+-3.24.0-doc
/gnu/store/3yrx79ds64dabi6qkkmh4s7ydiqxhl4g-gtk+-3.24.0
$ ls -l /gnu/store/0mskf7mzfrhrnkixfadrvvr5lgfssfzf-gtk+-3.24.0-bin/bin
