Sync our DTrace infrastructure with c.h's definition of type bool.

Since commitd26a810, we've defined bool as being either _Bool from<stdbool.h>, or "unsigned char"; but that commit overlooked the factthat 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'dbe better to write "#define bool _Bool". However, then we'd needsome build infrastructure to inject that configuration choice intoprobes.d, and it doesn't seem worth the trouble. We only use<stdbool.h> if sizeof(_Bool) is 1, so having DTrace think thatbool parameters are "unsigned char" should be close enough.Back-patch to v12 whered26a810 came in.Discussion:https://postgr.es/m/CAA4eK1LmaKO7Du9M9Lo=kxGU8sB6aL8fa3sF6z6d5yYYVe3BuQ@mail.gmail.com
