James Knight a940148989 board/qemu: restore readme globbing
The QEMU board's post-image script will glob through various
`readme.txt` files for an appropriate command line to use. Recent linter
changes [1] prevents this from happening, and results in the following
build error:

    >>>   Executing post-image script board/qemu/post-image.sh
    sed: can't read board/qemu/*/readme.txt: No such file or directory

Reverting part of the shellcheck fixes for the README file arguments and
marking a linter exception.
