Rework macro pgstat_is_ioop_tracked_in_bytes()

Browse Source 
As written, it was triggering a compilation warning for old versions of
clang, as reported by buildfarm members ayu, batfish and demoiselle.
Forcing a cast with "unsigned int" should fix the warning.

While on it, the macro is moved to pgstat.h, closer to the declaration
of IOOp, per suggestion from Tom Lane.
