[base-runner] no longer fail silently in test_one.py (#7776) 

It should make it easier to figure out why exactly
`./infra/helper.py check_build project fuzz-target` fails
by turning
```
INFO: performing bad build checks for /tmp/not-out/tmpa4lph9dr/fuzz-bus-message
ERROR:root:Check build failed.
```
into something like
```
INFO: performing bad build checks for /tmp/not-out/tmpa4lph9dr/fuzz-bus-message
BAD BUILD: /tmp/not-out/tmpa4lph9dr/fuzz-bus-message seems to have either startup crash or exit:
/tmp/not-out/tmpa4lph9dr/fuzz-bus-message -rss_limit_mb=2560 -timeout=25 -seed=1337 -runs=4 < /dev/null
/tmp/not-out/tmpa4lph9dr/fuzz-bus-message: error while loading shared libraries: libcap.so.2: cannot open shared object file: No such file or directory

ERROR:root:Check build failed.
