Sync our DTrace infrastructure with c.h's definition of type bool.
Since commit d26a810eb, we've defined bool as being either _Bool from
<stdbool.h>, or "unsigned char"; but that commit overlooked the fact
that probes.d has "#define bool char". For consistency, make it say
"unsigned char" instead. This should be strictly a cosmetic change,
but it seems best to be in sync.
Formally, in the now-normal case where we're using <stdbool.h>, it'd
be better to write "#define bool _Bool". However, then we'd need
some build infrastructure to inject that configuration choice into
probes.d, and it doesn't seem worth the trouble. We only use
<stdbool.h> if sizeof(_Bool) is 1, so having DTrace think that
bool parameters are "unsigned char" should be close enough.
Back-patch to v12 where d26a810eb came in.
