avoid unecessary call to package manager (#25399)

When building for an OS different from Linux, FreeBSD or SunOS, don't try to call a sytem package manager. It may actually install a useless OpenGL system library (ie unrelated to host OS) when build machine is Linux, FreeBSD or SunOS.

Also support SunOS by trying PkgUtil system package manager.
