libwebp-devel: do not depend on libfreeglut-devel
Although there is a (correct) makedepends on libfreeglut-devel, it is
only needed to compile the vwebp tool, so libwebp-devel should not
depend on it. This is very relevant since libfreeglut-devel deptree
includes a lot of unnecessary stuff (mesa, wayland, X libraries, etc.)

A patch file from https://github.com/void-linux/void-packages/pull/23659.patch is attached
