pgpool2: fix compiling for 32-bit arches

When compiling for 32-bit targets, two issues came to surface:

1. gcc was complaining that math.h is not included in snprintf, and some
   calls were implicitly defined. Added a patch that includes the required
   headers in snprintf.c file:

| snprintf.c: In function 'fmtfloat':
| snprintf.c:1232:13: error: implicit declaration of function 'isnan' [-Wimplicit-function-declaration]
|  1232 |         if (isnan(value))
|       |             ^~~~~
| snprintf.c:50:1: note: include '<math.h>' or provide a declaration of 'isnan'

2. The code passes a time_t argument to a function that expects a long. This works for
   64-bit targets, because on those usually time_t is long.
   However on 32-bit systems time_t is usually long long, which makes compilation fail
   with the following error:

| wd_json_data.c:540:66: error: passing argument 3 of 'json_get_long_value_for_key' from incompatible pointer type [-Wincompatible-pointer-types]
|   540 |         if (json_get_long_value_for_key(root, "StartupTimeSecs", &wdNode->startup_time.tv_sec))
|       |                                                                  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

   To account for this, add a new helper method in a patch that returns the required json value
   as a time_t value.

The patches are in pending state, because the mailing list of the project is sufferring from
technical problems - when the site loads, sign up attempts throw internal server errors.

It is planned to submit the patches and to update the status once their infrastructure is back.
