build: fix format errors

mostly trivial:

for s?size_t -> use z modifier
for long/int/time_t/pid_t: add explicit cast, or use different specifier
for char*/void*: use explicit cast

for too many/too few arguments, use git log and context to either

add format specifier or drop argument, resp.
drop format specifier or add suitable argument.
