042e8a44 - Make `requirements_txt_ssh_git_username` not write into homedir (#13857)

Make `requirements_txt_ssh_git_username` not write into homedir (#13857) ## Summary Modify `requirements_txt_ssh_git_username` test to pass `-o UserKnownHostsFile=/dev/null` to OpenSSH, in order to prevent it from trying to write into the known-hosts in user's home directory. To add insult to the injury, OpenSSH ignores `HOME` and writes into the actual home when it is explicitly overridden for the purpose of testing. ## Test Plan `cargo test --no-default-features --features=git,pypi,python` in an environment where the user can't write to `pw_home` (but can to `${HOME}`). Previously the test would fail: ``` ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Snapshot Summary ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Snapshot: requirements_txt_ssh_git_username Source: crates/uv/tests/it/export.rs:1252 ──────────────────────────────────────────────────────────────────────────────── Expression: snapshot ──────────────────────────────────────────────────────────────────────────────── -old snapshot +new results ────────────┬─────────────────────────────────────────────────────────────────── 7 7 │ ├─▶ failed to clone into: [PATH] 8 8 │ ├─▶ failed to fetch branch, tag, or commit `d780faf0ac91257d4d5a4f0c5a0e4509608c0071` 9 9 │ ╰─▶ process didn't exit successfully: [GIT_COMMAND_ERROR] 10 10 │ --- stderr 11 │+ Could not create directory '/var/lib/portage/home/.ssh' (Permission denied). 12 │+ Failed to add the host to the list of known hosts (/var/lib/portage/home/.ssh/known_hosts). 11 13 │ Load key "[TEMP_DIR]/fake_deploy_key": [ERROR] 12 14 │ git@github.com: Permission denied (publickey). 13 15 │ fatal: Could not read from remote repository. 14 16 │ ────────────┴─────────────────────────────────────────────────────────────────── ``` --------- Co-authored-by: konstin <konstin@mailbox.org>
