lib: fix conversion warnings for SOCKET_WRITABLE/READABLE
- If loss of data may occur converting a timediff_t to time_t and the time value is > TIME_T_MAX then treat it as TIME_T_MAX. This is a follow-up to 8843678 which removed the (time_t) typecast from the macros so that conversion warnings could be identified. Closes https://github.com/curl/curl/pull/5199
