Sunway inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I56P0Z
--------------------------------
We were relying on GNU nm's ability to extract our VDSO symbols, but newer nm will always display version strings after symbol names, which cause so2s.sh to fail to generate vdso-syms.S. Fix so2s.sh to make it work.
Besides, remove the copyright strings from so2s.sh.
