basic/log: fix _printf_ annotation on log_object_internalv

Fixup for 4b58153dd22172d817055d2a09a0cdf3f4bd9db3.

I saw this because of a clang warning. With gcc the -Wformat-nonliteral warning
doesn't seem to work as expected.

In two places, a string constructed with strjoina is used as the pattern. This
is safe, because we're taking a pattern which was already marked with _printf_
and prepending a known value to it.  Those places are marked with #pragma to
silence the warning.
