[LTP] [PATCH v1 1/1] keyctl05: improve the dns_res_payload for boundary testing

[Pengfei Xu]

Because the following patch will fix the add_key syscall incoming data boundary
size issue, 6 bytes incoming data should pass:
https://lore.kernel.org/all/1784441.1704907412@warthog.procyon.org.uk/
 -> https://lore.kernel.org/all/1850031.1704921100@warthog.procyon.org.uk/
In order to test above boundary incoming data size, change the dns_res_payload
size.
