[PATCH 2/2 v3] docs: rcu: Replace multiple dead OLS links in RTFP.txt

[Nikil Paul S <snikilpaul@gmail.com>]

This patch is a v3 update to the earlier "[PATCH 2/2] docs: rcu: Update
dead OLS link in RTFP.txt". In addition to fixing the OLS 2001 link from
v2, it also updates two more dead links from the OLS 2006 Proceedings.

Several references in RTFP.txt pointed to linuxsymposium.org, which is no
longer hosting the original documents. These have been replaced with
working copies hosted on kernel.org.

Changes since v2:
 - Updated two OLS 2006 abstract links in addition to the OLS 2001 link.
