replace libc::res_init with res_init_if_glibc_before_2_26
The previous workaround for gibc's res_init bug is not thread-safe on other implementations of libc, and it can cause crashes. Use a runtime check to make sure we only call res_init when we need to, which is also when it's safe. See https://github.com/rust-lang/rust/issues/43592.
