elf: Merge __dl_libc_freemem into __rtld_libc_freeres

Browse Source 
The functions serve very similar purposes.  The advantage of
__rtld_libc_freeres is that it is located within ld.so, so it is
more natural to poke at link map internals there.

This slightly regresses cleanup capabilities for statically linked
binaries.  If that becomes a problem, we should start calling
__rtld_libc_freeres from __libc_freeres (perhaps after renaming it).
