edac-utils: add patches for initscript

Update LIC_FILES_CHKSUM that the whole license file should be used
rather than the first 2 lines.

Remove COMPATIBLE_HOST that edac-utils could build for all architectures.

Update runtime dependencies:

* add perl modules that edac-ctl needs
* add dmidecode for the archs which are in COMPATIBLE_HOST of dmidecode
  that dmidecode is required by command edac-ctl.

And add patches for initscripts to:

* add restart subcommand
* make init script be able to load EDAC module automatically
