Unable to startup Spring Boot app running inside Docker

- [x] I have searched the [issues](https://github.com/alibaba/arthas/issues) of this repository and believe that this is not a duplicate.

### Environment

* Arthas version: 3.4.6
* Operating System version: Ubuntu Server 20.10
* Java version of target JVM: 11
* Java version of JVM used to attach: 11
* Spring Boot 2.3.7

### Steps to reproduce this issue

1. Embed Arthas in Spring Boot via "arthas-spring-boot-starter" Maven dependency
2. Create Docker container with "gradlew bootBuildImage"
3. Start Docker container

### Expected Result

Application starts up with Arthas enabled.

### Actual Result

Application crashes on startup:

### Hints

Works as expected when the Spring Boot app is started without Docker container.

Reproduce the Docker startup path from the issue, beginning with com.alibaba.arthas.spring.ArthasConfiguration.arthasAgent and com.taobao.arthas.agent.attach.ArthasAgent.init, then follow the reported ByteBuddyAgent.install failure. Done means the Spring Boot application starts with Arthas enabled inside the Docker image without the reported attachment-provider error.
