Avoid warnings about uninitialized variables in TGA loading code.

Initialize the variables containing the colour components: even though they
should normally be always filled by Palette_GetRGB() call below, this
presumably might not happen for a corrupted image with invalid palette table
entries and g++ correctly complains about it.

See #14459.
