libportal: fix rare build race

There is a build race where the libportal.vapi is not always generated
before it is needed to build libportal-gtk*.vapi. Backport the fix from
upstream.

+Subject: [PATCH] meson.build: fix build race when building GTK vapi files
+
+There's a build race when building the GTK vapi files:
+
+FAILED: libportal/libportal-gtk4.vapi
+error: Package `libportal' not found in specified Vala API directories or GObject-Introspection GIR directories
+
+This can be verified by adding "sleep 10;" to the command for the
+libportal/libportal.vapi target in the generated build.ninja file.
+
+The GTK vapi files need to have access to the generic libportal.vapi file,
+but there is no explicit dependency.  Switch the dependency name 'libportal'
+to the dependency object libportal_vapi so that Meson generates the
+dependency correctly.
+
+Upstream-Status: Backport
