Avoid confusing spec for Armenia in 2011

This does not change the zic output; it merely clarifies the input.
It also simplifies a future change that I have in mind.
* asia (RussiaAsia): Remove confusing discrepancy with Russia rule.
(Armenia): New rules for 2011 only, when Armenia disagreed with Russia.
(Asia/Yerevan): Use them.
