ELF: Create dynamic symbols for symbol aliases of copy relocations. For each copy relocation that we create, look through the DSO's symbol table for aliases and create a dynamic symbol for each one. This causes the copy relocation to correctly interpose any aliases. Copy relocations are relatively uncommon (on my machine, 56% of binaries in /usr/bin have no copy relocations probably due to being PIEs, 97% of them have <10, and the binary with the largest number of them has 97) so it's probably fine to do this in a relatively inefficient way.
