glibcompat: Provide implementation for G_GNUC_NO_INLINE

Currently, we require glib-2.56.0 at minimum (because of RHEL-8)
but we use G_GNUC_NO_INLINE which was introduced in 2.58.0. While
we provide an implementation for older versions, where the macro
does not exists, it's a bit more tricky than that. Since we
define GLIB_VERSION_MAX_ALLOWED we would get a compile time error
when trying to use something too new, except for G_GNUC_NO_INLINE
which was intentionally not marked as
GLIB_AVAILABLE_MACRO_IN_2_58. But this is about to change with
glib-2.73.2 (which contains commit [1]).

At the same time, we can't just bump glib and thus we have to
provide an alternative implementation without the version
annotation.
