Running a bunch of tests with `yes` is broken

[Serpentian]

Commit https://github.com/tarantool/test-run/commit/3b0ccd0721e5fc772faeab2481f52723d5b5a69d breaks running tests with:

./test-run.py --builddir=.. $(yes 7253 | head -100)

After this commit only one test is launched, which is unacceptable, as It's the only way to check, whether the test is flaky

Confirmed. Sorry for the inconvenience.

A temporary workaround is the following (needs patching test-run).
