include/prereq-build.mk: macOS cross build improvements
This updates prereq-build.mk to find a suitable realpath utility, and adds another place to look for a suitable getopt utility. realpath has been used most notably by scripts/ipkg-build since commit bb95be9265a9 ("scripts,ipkg-build: use realpath for pkg_dir") and there are assorted other uses of it during a build. It is ordinarily provided by GNU coreutils. This adds a SetupHostCommand to locate it either under its own name or under grealpath, the name that it will be available as under MacPorts or Homebrew, which use --program-prefix=g. Similarly, update the SetupHostCommand for getopt to be able to locate a util-linux getopt at the default path used by MacPorts, in the same fashion that commit cc16f5d73e77 ("build: try to find getopt in macOS homebrew's standard location")' did for Homebrew. As there is no standard alternative --program-prefix for util-linux utilities in the way that GNU packages often use a "g" prefix, this path-based approach is required in case a non-util-linux getopt (such as one provided by an OS) shadows the util-linux getopt in the PATH.
