Explicitly define __STDC_FORMAT_MACROS for PRIu64
Summary:
Builds are failing on RHEL machines because of PRIu64.
lvm/projects/compiler-rt/lib/gwp_asan/guarded_pool_allocator.cpp:420:50: error: expected ')'
`snprintf(ThreadBuffer, kThreadBufferLen, "%" PRIu64, ThreadID);`
inttypes.h in RHEL uses PRIu64 macros only when __STDC_FORMAT_MACROS is defined.
