a64_emit_x64: Ensure host has updated ticks in EmitA64GetCNTPCT

Browse source 
Discovered by @Subv.
Fixes incomplete fix begun in 5a91c94dca47c9702dee20fbd5ae1f4c07eef9df.
That fix fails to take into account that LinkBlock doesn't update ticks until there
are no remaining ticks to be executed.

Test added to confirm fix.
