    Fix regex builder

    Currently when the blacklist_file and regex string is provided,
    the constructed regex looks like '^((?!black1|black2|...).)*$regex'.
    This is incorrect, as it will match nothing - some string
    is expected after end of the line [denoted as $ in the regex].

    The proper construction is like ^(?!black1|black2|...).*(regex).*$
    This solves the issue with Tempest, where using blacklist for smoke
    tests is not working now, as it leads into the issue described above.
