bootchart: put the bootchart into the journal.
This bit of code is mostly stolen from coredump.c. We construct a simple journal message and append the bootchart file in the journal automatically. You can extract the latest bootchart from the current boot with something like: $ journalctl -b MESSAGE_ID=9f26aa562cf440c2b16c773d0479b518 --field=BOOTCHART which prints it to stdout. None of the other logic is touched. The journal entry is created even if bootchart was run manually, which is probably wrong.
