Issue:
import error if generate multiple proto
**Describe the bug**
当同时生成多个 proto 时，会有 import package 错误的问题，并且与执行的顺序有关

**To Reproduce**
Steps to reproduce the behavior, if applicable:

1. The code is
 - 第一次，先生成 protos/a/v1/a.proto，再生成 protos/b/v1/b.proto
   操作:

   import 错误:

2. The error is


**Expected behavior**
无论生成 proto 的顺序如何，import package 都应该是正确的

**Screenshots**
参见上面的图片

**Environments (please complete the following information):**
 - OS: [e.g. macOS]
 - go-zero version [e.g. 1.6.0]
 - goctl version [e.g. 1.6.0]
