It's shorthand for initializing to UINT_MAX.

For virTestGetFlag, we generally only care about 0 or 1; but since it
uses the same helper function of virTestGetFlag, which DOES care about
the numeric value (ie. VIR_TEST_DEBUG=2 gives more output than
VIR_TEST_DEBUG=1), that explains why the helper function returns an
integer, and why I copied that paradigm.

Thanks for the review; I'll push shortly as-is; I'm not sure it's worth
changing the types of these functions.
