timeval: Check for HAVE_BACKTRACE instead of HAVE_EXECINFO_H.

Other code in the tree uses HAVE_BACKTRACE and then blindly includes
<execinfo.h> if it is present, so this doesn't make anything worse.

Once we do that, HAVE_EXECINFO_H has no further users, so this commit also
removes the check for <execinfo.h>
