meson: Substitute DBUS_APIDOC_LINK

doc/index.html.in is common to the Meson and CMake build systems, so
every time a new variable gets substituted into it, both the Meson and
CMake build systems need to provide a value for that variable.

Fixes: b58ca0e1 "cmake: Inclusion of a link in html overview file corrected"
