Remove CloseHandle() from __archive_write_program_free

The call to CloseHandle() is asymmetric and wrong.

The handle is created during the __achive_create_child() call in
__archive_write_program_open() aka the filter open callback.

While CloseHandle() is already called in the filter close callback aka
__archive_write_program_close().

Remove the incorrect call to CloseHandle() from the bidder free callback
