Log:
  Fix the following -Werror warnings from clang 3.5.0, while building
  bsnmpd's snmp_hostres module:
  
  usr.sbin/bsnmpd/modules/snmp_hostres/hostres_snmp.c:204:20: error: absolute value function 'abs' given an argument of type 'const long' but has parameter of type 'int' which may cause truncation of value [-Werror,-Wabsolute-value]
          str[9] = (u_char)(abs(tm->tm_gmtoff) / 3600);
                            ^
  usr.sbin/bsnmpd/modules/snmp_hostres/hostres_snmp.c:204:20: note: use function 'labs' instead
          str[9] = (u_char)(abs(tm->tm_gmtoff) / 3600);
                            ^~~
                            labs

          str[10] = (u_char)((abs(tm->tm_gmtoff) % 3600) / 60);
                              ^

                              ^~~
                              labs
  
  Since tm::tm_gmtoff is a long, use labs(3) instead.
