syz-ci: fix seeds copying

1. Copy seeds from syzkaller checkout into syzkaller build dir.
   They need to be stable.

2. Make the code generic (current is linux-specific).

3. Don't copy seeds to workdir/seeds.
   We can load them directly from sys/OS/test.
   There are some unresolved comments for LinkDir on #2053 anyway.

Follow up to #2053
