Fix CONFIG variable being read incorrectly in setup-qt.js

QT_CONFIG was read in the line before CONFIG, and the regex matched it:

    QT_CONFIG += private_tests shared shared [...]
    CONFIG += shared shared debug sanitize_address sanitizer

This would lead to address sanitizer being ignored and requiring
workarounds.

Use a stricter regex that doesn't allow arbitrary characters before the
key. The regex can be tested manually here:
