fix: pass report_id directly to get_data_set_extra

[ozgen]

What

• Fixed unnecessary g_strdup() calls in several get_report_* parsers.
• The original attribute value is now passed directly to get_data_set_extra().
• Updated the same issue in reports like ports, applications, operating systems, vulnerabilities, and hosts.

Why

• get_data_set_extra() already duplicates the value internally.
• Calling g_strdup() before passing the value caused memory leaks.
• This fix keeps the same behavior and avoids the leaks.
