Linux kernel source SFS filtering

The SFS downloader and installer, SFSget, and the BootManager for choosing which SFSs to load, offer all the kernel source SFS files available online. However, there will only be one that is appropriate, that is the same kernel version as currently in use in Easy.

So, have applied filtering. Github commit:
