perf util: Add host_is_bigendian to util.h

Avoid libtraceevent dependency for tep_is_bigendian or trace-event.h
dependency for bigendian. Add a new host_is_bigendian to util.h, using
the compiler defined __BYTE_ORDER__ when available.

Committer notes:

Added:

 #else  /* !__BYTE_ORDER__ */

On that nested #ifdef block, as per Namhyung's suggestion.
