Resolves #9473
Using https://www.fileformat.info/format/tga/egff.htm as a reference, I found that v2 TGA files may has a 26 byte footer at the end of the file. The first 4 bytes point to the 'extension area', the last byte of which is 'AttributesType'. If this is zero, then the file should not has any alpha.
To avoid seeking to the end of the file during
open), I'm only checking this value inload_end(), and filling the alpha channel at that point.
