[PATCH v4 08/14] genksyms: adjust the output format to modpost

[Masahiro Yamada]

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.
