    stubom: newlib: Enable C99 formats for %z
    
    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.")
