In spite of there being considerable documentation sometimes in the
config file, we go with CC0 because we don't want the notion of
'derived work' of a config file.
The example `settings.conf` is also CC0. Add some docs to
it while we're at it.
- The mitigations are slightly intrusive, and may clash
with other, similar mitigations (especially for initramfs,
the recommended solution is to configure the system with
the snippet outside of Calamares).
- This is a simple variation on the theme of things-that-call-a-
initramfs-updater, so the code is mostly a copy of initramfs/
module. I didn't even bother to strip out the configuration-
handling (I figure it might be good for *something*) so now
"" and "$uname" are valid kernel names as well.
- Fixes security issue where the initramfs ends up readable
by all, and that includes the cryptfile for LUKS.

Module descriptors are now module.desc, no configuration allowed inside.
Module config files are <modulename>.conf, installed in
share/calamares/modules.
settings.conf is read from /etc/calamares, then share/calamares, and if
running with --debug also in the current dir.
Module config files are read from /etc/calamares/modules, then
share/calamares/modules, and if running with --debug also in
src/modules/<modulename> relative to the current dir.
