Fix macro definitions in pgstatfuncs.c
Buildfarm member wrasse has been complaining about empty declarations
as an effect of
8018ffb and
83a1a1b due to extra semicolons.
While on it, remove also the last backslash of the macros definitions,
causing more lines to be eaten in it than necessary, per comment from
Tom Lane.
