sysvinit: remove unused files

sysvinit: remove unused files

The 'need' and 'provide' files are there for simpleinit compatability,
according to the comments in these two files.

However, we don't use simpleinit and there's even no simpleinit recipe
in OE. Besides, these two files are not installed.

This patch removes these two unused files.
