runtime: convert g.waitreason from string to uint8
Every time I poke at #14921, the g.waitreason string
pointer writes show up.
They're not particularly important performance-wise,
but it'd be nice to clear the noise away.
And it does open up a few extra bytes in the g struct
for some future use.
This is a re-roll of CL 99078, which was rolled
back because of failures on s390x.
Those failures were apparently due to an old version of gdb.
