    scripts/CKC: don't output from shopt
    
    shopt outputs the status of the flag, so that git grep looks like:
    git grep -qi 'nocasematch     off
    ^References:.*bsc#1202195' remotes/origin/SLE15-SP2-RT -- 'patches.*'
    
    I don't know how it can work (it does -- maybe thanks to ^), but it's
    not definitely OK.
    
    So make shopt in term2regex() quiet.
