dlfcn: Eliminate GLIBC_PRIVATE dependency from tststatic2
The test appears to use _dlfcn_hook@@GLIBC_PRIVATE as a way to test dlvsym without having to know the appropriate symbol version. With <first-versions.h>, we can use a public symbol and the symbol version at which it was defined first. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
