server_detect incorrectly thinks drizzle built in May is MySQL

[Stewart Smith]

<stewart> boost::regex mysql_regex("(5\\.[0-9]+\\.[0-9]+)");
       boost::regex drizzle_regex("(20[0-9]{2}\\.(0[1-9]|1[012])\\.[0-9]+)");
 and....
 (gdb) p version
 $6 = {static npos = <optimized out>,
   _M_dataplus = {<std::allocator<char>> = {<__gnu_cxx::new_allocator<char>> = {<No data fields>}, <No data fields>}, _M_p = 0x6858d8 "2011.05.17.2308"}}
 mtaylor, i.e. the mysql regex matches :)
