Fix --logfile and message truncation issue.

Regression in 6.4.20's security fix (Git commit c546c829).

We doubly incremented partial_message_size_used on modern systems
(stdard.h/vsnprintf), once in report_vbuild() and then again in
report_build(), so the 2nd and subsequent report_build() fragments
landed too late in the buffer.  This will not cause overruns due to the
reallocation prior to the vsnprintf/sprintf, but it write starts behind
the '\0' byte, instead of right over it, so the string also gets
truncated to the first fragment written with report_vbuild().

Fix by moving the increment back into the #else...#endif part that does
not use report_vbuild().
