Jens Johansen eb956a2516 Add synthetic bit to Library flags ...

Fasta can generate synthetic libraries.
Previously we didn't include them when serializing, but that leaves
references in the binary to libraries that doesn't exist which isn't
ideal.

This change includes them, and adds a flag to kernel Libraries such that
we know they are synthetic.
