This change is inspired by commit openwrt/openwrt@38b22b1e ("nghttp2:
deduplicate files in libnghttp2")

The packages in this commit are identified with the following command

	grep -rin -E 'INSTALL_(DATA|BIN)' | grep -F '.so' | grep -F '*'

Some of them do not have symlinks and are not affected, but the change
is still applied for consideration of best practices just in case

Some of them forgot to update MIRROR_HASH on version change, others
updated with wrong hash value.  The new values were generated from
tarballs prepared by the newly introduced github-tarball download
methoded and confirmed consistent with those from sources.openwrt.org

From the package description:
PageKite is a system for running publicly visible servers (generally
 web servers) on machines without a direct connection to the Internet,
 such as mobile devices or computers behind restrictive firewalls.
 PageKite works around NAT, firewalls and IP-address limitations by
 using a combination of tunnels and reverse proxies.

 This package provides an implementation of the PageKite Protocol in C,
 optimized for high-performance or embedded applications.
