Fix potential memory leak in R_Upload8() in GL1.

Browse source 
This is a corner case, next to unlikely that anyone would have ever hit
it. That's why my tests with asan didn't find the leak. The if case are
paletted textures which must be enabled by setting `gl1_palettedtexture`
to 1 and requires an GPU with support for `GL_EXT_paletted_texture`.
Nvidia dropped support for that in 2005. Additionally a sky texture
must be uploaded.
