[PATCH] Fix use_texture_alpha for tracks Export this patch

The use of textures with transparent pixels (for the default tracks: the
"features" on the track) without specifying use_texture_alpha (at least
for the mesh drawtype) has been deprecated in a PR from August 2020[1]
(i.e. since 5.4.0[2]) and removed in the latest dev version[3]. As a
consequence, regular tracks are now rendered with black markers at the
same position where e.g. the blue (Lua)ATC marker would be found.

This commit fixes the issue by enabling use_texture_alpha by default for
all tracks.

Hi all,

No longer just a "dev" version problem, this affects the stable Minetest 
5.9.0. Any clients on that version or above will see ugly black "track 
equipment" (the boxes inside the tracks) and the usually-invisible 
"overhead powerline" geometry. I think it should be a priority to merge. 
Any player on 5.9.0 who downloads Advtrains off ContentDB or plays on a 
server without a patch on is not going to be impressed.
