Build ghc-iserv with --export-dynamic
This enables loading dynamic libraries that refer to the RTS. I just
came across somewhere I needed to do that, and without
`--export-dynamic` it's impossible.
For now we'll only support that when using `-fexternal-interpreter`,
because the dynamic symbol table for GHC itself is much bigger.
Test Plan: validate
