gnu: go-github-com-charmbracelet-x-termios: Use git-fetch/lfs.

The charmbracelet/x repository uses Git LFS for binary files (*.png, *.jpg,
*.ttf).  Using git-fetch/lfs ensures proper checkout of these files,
preventing hash mismatches across different architectures.

* gnu/packages/golang-xyz.scm (go-github-com-charmbracelet-x-termios): Use
git-fetch/lfs method.
