SpringBoot Image building fails during cleanup when bind mount has read-only content

We're seeing failures like this on CI:

Caused by: java.nio.file.AccessDeniedException: /tmp/junit-image-pack-gradle-10097551270091885690-work-layers/spring-boot_test-info

    at org.springframework.boot.buildpack.platform.build.Lifecycle.deleteBind(Lifecycle.java:324)

spring-boot_test-info is read-only which prevents it from being deleted.
