loader_open_render_node returns the first device in /dev/dri that it
can use. To make sure the drm-shim device always gets chosen, return
the fake entries in readdir before returning the real ones.

When I was writing drm-shim, I was focused on the v3d kmsro case -- use my
intel device as the kmsro display device and add on a simulator-based v3d
device that we could render with. But for the noop backends we use for
shader-db, it's a lot more useful to just overwrite the first render node
in the system so that you don't have to pass a -d <how many render nodes I
already have in my system> argument.

Close input end of the pipe after data was written. Without this
fix I have seen a hang in sysfs_uevent_get(.., "OF_FULLNAME")
when key was not found.

The goal is to enable testing of parts of drivers without depending on any
particular kernel version or hardware being present.
Simply set LD_PRELOAD=$PREFIX/lib/libv3d_drm_shim.so in your environment,
and we'll fake a /dev/dri/renderD128 (or whatever the next available node
is) using v3dv3. That node can then be used with the surfaceless or gbm
EGL platforms.
