move static-linked stub dlsym out of dynlink.c

the function name is still __-prefixed because it requires an asm
wrapper to pass the caller's address in order for RTLD_NEXT to work.

since this was the last function in dynlink.c still used for static
linking, now the whole file is conditional on SHARED being defined.
