[Skiboot] generate-fwts-olog error

[Stewart Smith]

When running fwts with my updated olog.json:

Regex HDAT: Bad timebase size [0-9]+ @ (?:0x[0-9a-f]+|nil) failed to compile:
13.

On this snippet:

  {
   "advice": "HDAT described an invalid size for timebase, which means there's a disagreement between HDAT and OPAL. This is most certainly a firmware bug.",
   "compare_mode": "regex",
   "label": "HDATBadTimebaseSize",
   "log_level": "LOG_LEVEL_CRITICAL",
   "pattern": "HDAT: Bad timebase size [0-9]+ @ (?:0x[0-9a-f]+|nil)"
  },
