Add libx11 to openSUSE build dependencies (#35553)

building on opensuse fails without `libx11-devel`

**Repro:**

```bash
$ cd $(mktemp -d)
$ git clone https://github.com/zed-industries/zed .
$ docker run --rm -it -v $(pwd):/zed -w /zed opensuse/tumbleweed

(opensuse) $ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
(opensuse) $ ./script/linux
(opensuse) $ cargo build --release
```

**Expected:** to work

**Actual:** 

```

  The system library `x11` required by crate `x11` was not found.
  The file `x11.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  The PKG_CONFIG_PATH environment variable is not set.

  HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing `x11.pc`.

  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
