        src/usr.bin/jot: jot.c

Log Message:
Generate format after setting the prec value

Otherwise we end up with setting invalid printf format: "%.-1f" (from
"if (snprintf(p, sz, "%%.%df", prec) >= (int)sz)") for prec equal to -1,
which is not canonical (rejected by gcc and clang when used explicitly).

Detected by ASan (MKSANITIZER) for "jot 8".
