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
