build: don't execute native2ascii-maven-plugin on every run as we don't modify translations frequently.

As "native2ascii" profile gets activated before executing any goals, this
leads to a non-obvious outcome that "mvn clean <some goal>" command
doesn't process resources. It happens because "native2ascii" profile
doesn't get activated as the target/classes/ru/mystamps/i18n directory
exists in the begginning and hasn't been removed yet.

As a workaround you might use:
- mvn -Pnative2ascii clean <some goal>
- mvn clean; mvn <some goal>
