Remove searchidx1001 from scap targets

searchidx* already has a cron that copies the required configuration
directly from tin rather than the local /usr/local/apache/common/*

Fun tip: we only need the messages files, InitialiseSettings and
all.dblist. The rest of MW is unused.

Copying to /usr like it's an Apache is pointless and doesn't acheive
anything other than filling up / and spamming IRC with low disk
warnings.
