Subject: [PATCH v3 10/15] genksyms: adjust the output format to modpost

From: Masahiro Yamada <[email-masked]>
Date: Thu, 5 May 2022 16:22:39 +0900

Make genksyms output symbol versions in the format modpost expects,
so the 'sed' is unneeded.

This commit makes *.symversions completely unneeded.

I will keep *.symversions in .gitignore and 'make clean' for a while.
Otherwise, some people might be upset with 'git status'.
