[PATCH] sysctl: documentation: fix table format warning

[Randy Dunlap]

Fix malformed table warning in sysctl documentation:
(don't use ':'s)

Documentation/admin-guide/sysctl/kernel.rst:798: WARNING: Malformed table.
Text in column margin in table line 7.

=====  ============================================
bit 0  print all tasks info
bit 1  print system memory info
bit 2  print timer info
bit 3  print locks info if ``CONFIG_LOCKDEP`` is on
bit 4  print ftrace buffer
bit 5: print all printk messages in buffer
bit 6: print all CPUs backtrace (if available in the arch)

Fixes: 934d51cad60c ("docs: sysctl/kernel: add missing bit to panic_print")
Fixes: addc64999934 ("panic: add option to dump all CPUs backtraces in panic_print")
