[Skiboot] [PATCH] fwts/generate-fwts-olog: Fix regex matches to allow more printf formats

[Jeremy Kerr]

We currently aren't handling the 'll' length modifier, or widths
starting with zero (eg %016x). The former is becase we have the shorter
'l' match in the group first (so borking on the second l). The latter is
because we don't allow a leading zero on width matches.

This change fixes those issues.
