rts: fix build failure on OpenBSD (_DYNAMIC symbol collision)
Summary:
Build failure on OpenBSD-6.4 the the following:
```
rts/RtsSymbols.c:994:1: error:
error: redefinition of '_DYNAMIC' as different kind of symbol
|
994 | RTS_OPENBSD_ONLY_SYMBOLS
| ^
RTS_OPENBSD_ONLY_SYMBOLS
^
```
On OpenBSD `_DYNAMIC` was always defined in `<elf.h>` headers
but used not to be included.
The change explicitly includes `<elf.h>` as a source of symbol definition.
