docs: add coredumpctl

Browse Source 
systemd-coredumpctl collects core files for later analysis
with gdb.  It's a convenient thing if the keys you use to encrypt
/var/lib/systemd/coredump are the same as the keys you use to encrypt
the filesystem where you're running bees.

Add it to the documentation just before the hand-rolled version.
