    bhyve: add helper to append a basl table without a header
    
    The common style for build an ACPI table will be:
    
    1. basl_table_create
    2. basl_table_append_header
    3. setup an ACPI_TABLE_* struct
    4. basl_table_append_bytes (without header)
    
    Add a helper for the last step.
