[PATCH 3/9] stubom: newlib: Enable C99 formats for %z

[Jason Andryuk <jandryuk@xxxxxxxxx>]

vtpmmgr was changed to print size_t with the %z modifier, but newlib
isn't compiled with %z support.  So you get output like:

root seal: zu; sector of 13: zu
root: zu v=zu
itree: 36; sector of 112: zu
group: zu v=zu id=zu md=zu
group seal: zu; 5 in parent: zu; sector of 13: zu
vtpm: zu+zu; sector of 48: zu

Enable the C99 formats in newlib so vtpmmgr prints the numeric values.

Fixes 9379af08ccc0 "stubdom: vtpmmgr: Correctly format size_t with %z
when printing."

I haven't tried, but the other option would be to cast size_t and avoid
%z.  Since this seems to be the only mini-os use of %z, that may be
better than building a larger newlib.
