terminal: Only set title if asprintf succeeded

Handles potential out of memory situation by skipping the title update.
This fixes the following warning:

  terminal.c: In function ‘resize_handler’:
  terminal.c:851:11: warning: ignoring return value of ‘asprintf’,
  declared with attribute warn_unused_result [-Wunused-result]
