[AURON #2439] Add git to yum install

[cxzl25]

Which issue does this PR close?

Closes #2439

Rationale for this change

https://github.com/apache/auron/actions/runs/30325123247/job/90213501717

build-release-1  | [ERROR] [mvn-builder-auron-core] ./dev/vendors/setup-vendors.sh: line 135: git: command not found

What changes are included in this PR?

1. dev/docker-build/centos7/Dockerfile: install git alongside the other build tools
   (it was previously missing entirely, causing setup-vendors.sh to fail with
   git: command not found).
2. dev/vendors/setup-vendors.sh: replace git -C "${target_dir}" apply --3way "${patch}"
   with (cd "${target_dir}" && git apply --3way "${patch}"), so patch application no longer
   depends on a git version >= 1.8.5.
3. .github/workflows/build-amd64-releases.yml: add dev/docker-build/centos7/Dockerfile to
   the paths trigger list so changes to the build image are validated by this workflow on PRs.

Are there any user-facing changes?

Thanks for the contribution! The changes look reasonable and address the missing git dependency. However, the Build amd64 Releases workflow is still failing, so could you please check the failure and confirm that the original git: command not found issue has been resolved? Also, please complete the “What changes are included” and generative AI disclosure sections in the PR description.
