Avoidable compiler warnings in `EventLog.c`

Summary

As of 2057c77d, the EventLog.c code uses FMT_Int to print C-int values cast to (long long) for no particular reason. On LP64-systems FreeBSD defines PRId64 as ld, not lld, and compiler warnings are generated for the code in question. A simple fix is below. There is no need for either FMT_Int or the casts to (long long). Just print the int values with %d:

Steps to reproduce

Build GHC 9.4.4 on FreeBSD 12.3

Expected behavior

Avoid the compiler warnings.
