scripted-diff: [validation] Rename CheckInputs to CheckInputScripts

Browse Source 
CheckInputs() used to check no double spends, scripts & sigs and amounts. Since
832e0744cb, the double spend and amount checks
have been moved to CheckTxInputs(), and CheckInputs() now just validates
input scripts. Rename the function to CheckInputScripts().

-BEGIN VERIFY SCRIPT-
sed -i -E -e 's/CheckInputs\b/CheckInputScripts/g' $(git grep -l CheckInputs | grep -v doc/)
-END VERIFY SCRIPT-
