Bug#52172 test binlog.binlog_index needs --skip-core-file to avoid leaving core files

For crash testing: kill the server without generating core file.

include/my_dbug.h
  Use kill(getpid(), SIGKILL) which cannot be caught by signal handlers.
  All DBUG_XXX macros should be no-ops in optimized mode, do that for DBUG_ABORT as well.
sql/handler.cc
  Kill server without generating core.
sql/log.cc
  Kill server without generating core.

/*
Make the program fail, without creating a core file.
abort() will send SIGABRT which (most likely) generates core.
Use SIGKILL instead, which cannot be caught.
We also pause the current thread, until the signal is actually delivered.
An alternative would be to use _exit(EXIT_FAILURE),
but then valgrind would report lots of memory leaks.
