style(tests): apply ruff auto-fix on _macos_port hwid

`ruff-format` collapses the multi-line implicit string concatenation
in `_macos_port`'s hwid argument onto a single line. No semantic
change — just keeps the file conformant with the project's
configured line-length and the implicit-string-concatenation style
ruff enforces. Pre-commit was running clean afterwards.
