The meson 0.60.0 release introduced a bug with the '/' operator when
using an empty path component. '/foo' / ''  will now result in '/foo'
not '/foo/'

  https://github.com/mesonbuild/meson/issues/9450

This breaks libvirt because xsltproc requires the trailing '/' on the
output directory path. Fortunately the explicit 'join_paths' function
is not affected by the regression
