[llvm-objcopy] Add support for special section indexes in symbol table greater than SHN_LORESERVE
As is indexes above SHN_LORESERVE will not be handled correctly because
they'll be treated as indexes of sections rather than special values
that should just be copied. This change adds support to copy them
though.
