psd: Fix alpha blending
...
PSD files are saved with as alpha premultiplied. The problem is that alpha refers to white instead of black so it requires transformation formulas. Then, to conver PS premultiplied to QImage premultiplied you have to use the following formula:
* V = Alpha + Vps - Max (C, M, Y, K, R, G, B, Gray, L\* components)
* V = Vps + (Alpha - Max + 1) / 2 (a\*, b\* components)
Where Max is the maximum value depending on the image depth and Vps is the valued read from the file.

raw: tweak seek implementation
...
libraw uses fseek when doing files, which allows seeking past the end
without problems, so do the same, otherwise when we report oss-fuzz
issues they say "give me an example to reproduce" and since our seek
and their seek don't behave the same it's hard to convince them
to fix their code
