| Boot with an unsecurable libvips unless the processor uses it (#58734)
Since cd0a2588, loading `active_storage/vips` at boot raised whenever
ruby-vips was installed but libvips or ruby-vips was too old to block the
unfuzzed loaders. That stopped `:mini_magick` applications from booting
even though Active Storage never hands them content through libvips.
Keep loading ruby-vips and calling `Vips.block_untrusted(true)` at boot for
every processor, and raise only where libvips is used: when the Vips
transformer loads, and when the Vips analyzer reads an image.
