Fix clang string-plus-int warning

Clang 8 warns about adding a string to an int does not append to the
string. Indeed it doesn't, but that was not the intention either. Use
array indexing as suggested to silence the warning. There should be no
functional changes.

The full warning message was:

    smtp.c:1221:29: warning: adding 'int' to a string does not append to the string [-Wstring-plus-int]
          eob = strdup(SMTP_EOB + 2);
