ci: Avoid CI failures from temp env file reuse #29441

1. 
   maflcko commented at 3:16 pm on February 16, 2024: member

   • Currently, running separate CI tasks at the same time may intermittently fail, because they race to read/write /tmp/env. Fix this by adding $CONTAINER_NAME to the file name.

   • Also, add $USER, while touching the line, to allow different users to run the same CI task at the same time.

   • Also, skip the git install if there is no need.

   Ref: https://github.com/bitcoin/bitcoin/pull/29274

2. ci: vary /tmp/env c65fde4831
3. ci: Skip git install if it is already installed

   This also avoids the sudo requirement for self-hosted CI runners.

    git is still installed unconditionally, otherwise, it wouldn’t be present, no?

    Might replace “install” with “require” if I re-touch, or in a follow-up?

    Post merge ACK https://github.com/bitcoin/bitcoin/commit/fa91bf2559d2e839592bf1dc1d423d5fb1c3573e.

    I ran multiple CI jobs at the same time and observed the nicer naming in the /tmp directory.
