build: meson: fix generation of api docs

We need to copy all introspection files to the same directory when
building the documentation.

Note that we only require Meson 0.44, but for the documentation at
least 0.46 is needed because of a new functionality of
gnome.gdbus_codegen(). In this way we can still build on Travis CI
(without documentation).
