util/log: Remove qemu_log_close

The only real use is in cpu_abort, where we have just
flushed the file via qemu_log_unlock, and are just about
to force-crash the application via abort.  We do not
really need to close the FILE before the abort.

The two uses in test-logging.c can be handled with
qemu_set_log_filename_flags.
