Subject: [PATCH 1/3] docs: sysctl/kernel: Add missing bit to panic_print

Commit de6da1e8bcf0 ("panic: add an option to replay all the printk message in buffer")
added a new bit to the sysctl/kernel parameter "panic_print", but the
documentation was added only in kernel-parameters.txt, not in the sysctl guide.

Fix it here by adding bit 5 to sysctl admin-guide documentation.
