librsvg: don't try to run target code at build time

The rsvg-loader test binary isn't installed but building it causes a mix
of build host and target code to be executed.  As we don't install the
test, don't build it.

+Subject: [PATCH] Don't build rsvg-loader in cross builds
+
+This binary is a non-installed test binary that isn't any use in cross builds, and
+causes problems because it generates a gdk-pixbuf loader cache at build time using
+a mix of host and target libraries.
+
+As we don't install the binary, we can just not build it.
+
+Upstream-Status: Inappropriate [upstream has moved to Meson]
