~/src/patches/: Clean up orphaned patches, duplicates and application patches outside existing directory structures

This patch represents the first batch of various patches we do not use
anymore, hence there is no sense in keeping them, polluting ~/src/patches/.

Two coreutils patches have been moved into the already existing
coreutils folder, while one libloc patch has been a duplicate to that
one already existing in ~/src/patches/libloc/.

Cleaning up this dump remains a non-exhaustive attempt, though. There
are several other patches I could not locate in LFS files in the first
place, which means that the amount of files we can drop from this
directory is likely to be greater than this patch currently covers.
