build: disable -Wformat-truncation warning

The warning seems questionable and overly strict.
For now, just disable it to allow building with gcc7.

    src/systemd/src/basic/time-util.c: In function ‘format_timespan’:
    src/systemd/src/basic/time-util.c:509:46: error: ‘%0*lu’ directive output between 1 and 2147483648 bytes may cause result to exceed ‘INT_MAX’ [-Werror=format-truncation=]

                                                  ^~~~
