[llvm] [Github] Add git to actions container image (PR #80341)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/80341

This patch adds git to the actions container image. This is not necessarily needed for actions/checkout (as it will fallback to downloading a tar archive), but is good to have for that in addition to any future operations that might need git. In addition, the LLVM CMake configuration throws some warnings when Git is not installed.

This patch also removes a slash from LLVM_SYSROOT. This is cosmetic as /opt/llvm//bin (which showed up on $PATH) is equivalent to /opt/llvm/bin, but the latter is canonical.

Subject: [PATCH] [Github] Add git to actions container image

This patch adds git to the actions container image. This is not
necessarily needed for actions/checkout (as it will fallback to
downloading a tar archive), but is good to have for that in addition to
any future operations that might need git. In addition, the LLVM CMake
configuration throws some warnings when Git is not installed.

This patch also removes a slash from LLVM_SYSROOT. This is cosmetic as
/opt/llvm//bin (which showed up on $PATH) is equivalent to
/opt/llvm/bin, but the latter is canonical.
