BUG/MINOR: tcpcheck: Fix typo in error error message for `http-check expect`

With a config:

    backend bk_app
    	http-check expect status 200 string "status: ok"

This now correctly emits the error:

    config : parsing [./patch.cfg:2] : 'http-check expect' : only one pattern expected.

This line containing the typo is unchanged since at least HAProxy 2.2, the
patch should be backported into all supported branches.
