[libcxx-commits] [libcxx] [libcxx] Add user to linux-builder docker image (PR #228933)

[Aiden Grossman via libcxx-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/228933

Accidentally didn't move this over when copying from the builder-base image in 84812cba90fe0a0f95544a3ff01da1e61346a68d. Without these we run as root by default which results in not throwing permission denied errors when running the test suite.

Subject: [PATCH] [libcxx] Add user to linux-builder docker image

Accidentally didn't move this over when copying from the builder-base
image in 84812cba90fe0a0f95544a3ff01da1e61346a68d. Without these we run
as root by default which results in not throwing permission denied
errors when running the test suite.
