Fix -Wformat error in Win-Clang build

Fix -Wformat error in Win-Clang build

rtc::PlatformThreadId is pid_t (32-bit signed int) on Linux and Mac,
but DWORD (32-bit unsigned int) on Windows.

Using the %d printf specifier is therefore not correct on Windows,
and Clang would warn about it:

..\..\third_party\webrtc\base\event_tracer.cc(124,46) :  error: format specifies
type 'int' but the argument has type 'rtc::PlatformThreadId' (aka 'unsigned
long') [-Werror,-Wformat]
                e.phase, e.timestamp, e.pid, e.tid);
                                             ^~~~~

This commit fixes the problem by explicitly casting to int before printing.
