'time' package adds 'syscall/js' dependencies to wasip1 build

[falconandy]

tinygo version 0.34.0 linux/amd64 (using go version go1.23.4 and LLVM version 18.1.2)

Without time package:

package main

//go:wasmexport add
func add(a, b int32) int32 {
	//_ = time.Time{}
	return a + b
}

func main() {}

GOOS=wasip1 GOARCH=wasm tinygo build -o ./wasmtest.wasm -buildmode=c-shared --no-debug -scheduler=none .

Result size: 9563 bytes

With time package:

package main

import (
	"time"
)

//go:wasmexport add
func add(a, b int32) int32 {
	_ = time.Time{}
	return a + b
}

func main() {}

GOOS=wasip1 GOARCH=wasm tinygo build -o ./wasmtest.wasm -buildmode=c-shared --no-debug -scheduler=none .

Result size: 13698 bytes

Is it intended to have syscall/js dependencies in wasip1 builds?

I can confirm this happens when relying on GOOS=wasip1 GOARCH=wasm, but it does not happen when passing -target=wasip1. Same as in #4439. (It's not specific to the time package.)

Occurs both on 0.34.0 and 0.35.0.
