[libnftnl PATCH 1/5] expr: queue: Add nft_rule_expr_queue_snprinf_* functions

[Ana Rey <anarey@gmail.com>]

Code refactoring in nft_rule_expr_queue_snprinf functions. This process
adds three new functions:

* nft_rule_expr_queue_snprinf_default
* nft_rule_expr_queue_snprinf_xml
* nft_rule_expr_queue_snprinf_json

Also, It is delete an unnecesary whitespace as the CodingStyle recommends.
