test: avoid noise in CI logs #30264

Browse Source 
Problem:
Since 96128a5076 the test logs have noise from tests that *expect*
failures:

    $NVIM_LOG_FILE: /tmp/cirrus-ci-build/build/.nvimlog
    (last 100 lines)

Solution:
Rewrite the test to use `vim.system()`. Set NVIM_LOG_FILE in the child
process to a "throwaway" logfile.
