Fix casing of libX11-devel SUSE package in script/linux (#64411)

## Objective

`libx11-devel` is not a valid package name in SUSE: it should
be`libX11-devel` (_should be a capital X!_).

source: [RPM resource
libX11-devel](https://rpmfind.net/linux/rpm2html/search.php?query=libX11-devel)

## Testing

- [x] Did you test these changes? If so, how?
- Tested on SLES 15.7 an [openSUSE
Tumbleweed](https://software.opensuse.org/package/libX11-devel)
  - `script/bundle-linux` succeeds
