In the early days of TinyGo, the idea of `postinit` was to enable interrupts only after initializers have run. Which kind of makes sense... except that `time.Sleep` is allowed in init code and `time.Sleep` requires interrupts to be enabled. Therefore, interrupts must be enabled while initializers are being run. This commit simply moves the enabling of interrupts to a point right before running package initializers. It also removes `runtime.postinit`, which is not necessary anymore (and was only used on AVR).
