bug#43296: [PATCH] gnu: Fix gnome-builder build.

[Leo Prikler <leo.prikler@student.tugraz.at>]

As reported in #43296, gnome-builder tries to be linked against the static
version of libselinux (propagated through glib/gio), failing to do so, as it
also wants to be a PIE.  To keep the PIE, link it against the dynamic library.
* gnu/packages/gnome.scm (gnome-builder)[#:phases]: Add 'fix-ninja.
