PEL: Print Failing MTMS section into JSON

Remove any trailing whitespace for serial number.

"Failing MTMS": {
    "Section Version":          "1",
    "Sub-section type":         "0",
    "Created by":               "0x4552",
    "Machine Type Model":       "OPWR-131",
    "Serial Number":            "1318ABA"
},

Testing: Manually run peltool and verified output. All unit tests
passed.
