fix: compute aura expirationTime for addon countdown timers

Browse source 
The expirationTime field (7th return value of UnitBuff/UnitDebuff/UnitAura)
was hardcoded to 0. Now returns GetTime() + remaining seconds, matching
WoW's convention where addons compute remaining = expirationTime - GetTime().
Enables buff/debuff timer addons like OmniCC and WeakAuras.
