contrib/check-config: fix MEMCG_SWAP

Browse Source 
CONFIG_MEMCG_SWAP has been deprecated since kernel v5.8-rc1 (commit 2d1c498) and removed since kernel v6.1-rc1 (commit e55b9f9).

Since kernel v5.8-rc1, swap tracking has been an integral part of memory control. CONFIG_MEMCG_SWAP becomes invisible to user and simply means CONFIG_MEMCG && CONFIG_SWAP. 

Disable the check for kernel v5.8+.
