  [ELF] --wrap: Drop __real_ symbol from the symbol table

In D34993, we discussed and concluded that we should drop `__real_
symbol from the symbol table, but I did the opposite in D50569.
This patch is to drop `__real_` symbol.

MaskRay's note: omitting `__real_` is important if it is undefined:
otherwise a subsequent link may error due to the undefined `__real_` in .dynsym
