Add missing JSON tags for NoncurrentVersionExpiration struct

[kaankabalak]

The omission of the missing JSON tags on the NoncurrentVersionExpiration struct was causing the default value of NoncurrentDays to be shown even when it was not being entered.

Steps to reproduce:
1- Build mc with the latest version of minio-go. Then verify that NoncurrentDays is shown as 0 even when it is not entered.

$ cat test1.json
{
  "Rules": [
   {
    "ID": "chhjo4um3rd3sheeultg",
    "NoncurrentVersionExpiration": {
     "NewerNoncurrentVersions": 1
    },
    "Status": "Enabled"
   }
  ]
 }
$ ./mc ilm  import play/test < ~/test1.json
Lifecycle configuration imported successfully to `play/test`.
$ ./mc ilm  export play/test 
{
 "Rules": [
  {
   "ID": "chhjo4um3rd3sheeultg",
   "NoncurrentVersionExpiration": {
    "NoncurrentDays": 0,
    "NewerNoncurrentVersions": 1
   },
   "Status": "Enabled"
  }
 ]
}

2- Build mc with this branch of minio-go. Then verify that NoncurrentDays is not shown when it is not entered.

$ cat test1.json
{
  "Rules": [
   {
    "ID": "chhjo4um3rd3sheeultg",
    "NoncurrentVersionExpiration": {
     "NewerNoncurrentVersions": 1
    },
    "Status": "Enabled"
   }
  ]
 }
$ ./mc ilm  import play/test < ~/test1.json
Lifecycle configuration imported successfully to `play/test`.
$ ./mc ilm  export play/test 
{
 "Rules": [
  {
   "ID": "chhjo4um3rd3sheeultg",
   "NoncurrentVersionExpiration": {
    "NewerNoncurrentVersions": 1
   },
   "Status": "Enabled"
  }
 ]
}
