    bash scripts: replace '[ ]' with '[[ ]]' for bash scripts

    kdumpctl, mkdumprd, *-module-setup.sh only target bash, since they
    only run in first kernel and depend on dracut, and dracut depends
    on bash. So use '[[ ]]' to replace '[ ]'.

    This is a batch update done with following command:
    `sed -i -e 's/\(\s\)\[\s\([^]]*\)\s\]/\1\[\[\ \2 \]\]/g' kdumpctl, mkdumprd, *-module-setup.sh`
    and replaced [ ... -a ... ] with [[ ... ]] && [[ ... ]] manually.

    See https://tldp.org/LDP/abs/html/testconstructs.html for more details
    on '[[ ]]', it's more versatile, safer, and slightly faster than '[ ]'.

    This will also help shfmt to clean up the code in later commits.
