test(web_server): make profile-wrapper alias test OS-aware

On Windows, hermes writes writer.bat (@echo off / hermes -p writer %*)
with CRLF endings instead of the POSIX writer shell script. The test
hardcoded the POSIX path and exact bytes, so it failed on Windows hosts.
Assert on stripped non-empty lines per platform, making it line-ending-
and OS-independent.
