Remove note about the decade old path migration to /sys and /var/lib

[danderson]

Front and center at the start of the book is a notice about a path migration from /selinux to /sys/fs/selinux, and from /etc/selinux/<TYPE>/module to /var/lib/selinux/<TYPE>. The former change happened in Fedora 17, released in 2012 (12 years ago). The latter was in Fedora 23, released 2015 (9 years ago).

As far as I could find, there are no mainline linux distros that still support releases that old, except maybe for RHEL 7, and then only for customers who pay for the "extended extended" life support contract, for everyone else it hit EOL earlier this year. If they're the only ones left, it seems reasonable to let Redhat handle it in their own documentation.

I think it's reasonable to call the migration "complete" by now, and not distract new SELinux users with it :)

Thanks for the PR!

I think now is a reasonable enough time to remove this old workaround. Just a small comment in the PR, that the paragraph above the table introducing it needs to be dropped as well.

Thanks for the patch! I'm going to leave this up over the holidays in case another maintainer has comments. Assuming nothing comes up, I'll merge it in January.
