8254270: linux 32 bit build doesn't compile libjdwp/log_messages.c

[omikhaltsova]

I'd like to backport JDK-8254270 to jdk13u for parity with jdk11u.
The same issue was observed while compiling for the Linux 32 bits platform (compiled with --disable-warnings-as-errors):

/home/ec2-user/workspace/zulu13-build-linux32/zulu-src.git/src/jdk.jdwp.agent/share/native/libjdwp/log_messages.c:82:29: warning: '%s' directive output may be truncated writing up to 56 bytes into a region of size between 52 and 76 [-Wformat-truncation=]
                    "%s.%.3d %s", timestamp_date_time,
                             ^~
                    (int)(millisecs), timestamp_timezone);
                                      ~~~~~~~~~~~~~~~~~~
/home/ec2-user/workspace/zulu13-build-linux32/zulu-src.git/src/jdk.jdwp.agent/share/native/libjdwp/log_messages.c:81:11: note: 'snprintf' output between 6 and 86 bytes into a destination of size 81
     (void)snprintf(tbuf, ltbuf,
           ^~~~~~~~~~~~~~~~~~~~~
                    "%s.%.3d %s", timestamp_date_time,
                    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                    (int)(millisecs), timestamp_timezone);
                    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

After applying this patch the problem has gone. The original patch applied cleanly. All regular tests passed.
