Update lifetimes of anti-deuteron, -triton and -alpha

The zero-lifetime of the anti-deuteron currently present in the ParticleTable leads to warnings issued by the ParticleClassificator. To avoid any other possibly related effects in the upcoming restripping campaign, the anti-deuteron lifetime is set to the same value as the deuteron one. The lifetimes of anti-triton and -alpha are modified in the same way for consistency.
