libtool: symlink correctly on darwin (#7179)

To accommodate build systems on Darwin which look for glibtool/ize,
#7060 attempted to provide glibtool/ize symlinks for libtool/ize
but accidentally created the same symlink twice. #7073 reverted this
and replaced libtool/ize with glibtool/ize on Darwin. This led to
#7163 since AutotoolsPackages depend on the presence of the 'libtool'
binary, so this returns to the approach of #7160 but makes the
correct symlinks.
