Subject: [PATCH] gnome: Fix gtkdoc generation

install_scripts used to replace @BUILD_ROOT@ and @SOURCE_ROOT@ but it
was not documented and got removed in Meson 0.58.0. gnome.gtkdoc() was
relying on that behaviour, but it has always been broken in the case the
source or build directory contains spaces.

Fix this by changing get_include_args() to substitue paths directly
which will then get escaped correctly.

Add a unit test that builds GObject documentation which is where this
issue has been spotted.

Fixes: #8744
Upstream-Status: Backport
