Subject: [PATCH v4 08/14] genksyms: adjust the output format to modpost
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, 'git status' might be surprising.
