tracing: Show module names and addresses of last boot

Add the last boot module's names and addresses to the last_boot_info file.
This only shows the module information from a previous boot. If the buffer
is started and is recording the current boot, this file still will only
show "current".

  ~# cat instances/boot_mapped/last_boot_info
  10c00000		[kernel]
  ffffffffc00ca000	usb_serial_simple
  ffffffffc00ae000	usbserial
  ffffffffc008b000	bfq

  ~# echo function > instances/boot_mapped/current_tracer
  ~# cat instances/boot_mapped/last_boot_info
  # Current
