fix(vim.system): invalid MAX_TIMEOUT for 32-bit systems #31638

The maximum signed value on 32-bit systems is 2 ^ 31 - 1. When using 2 ^ 31 for
the default timeout, the value would overflow on such systems resulting in
a negative value, which caused a stack trace when calling wait() without
a timeout.
