Make global blocked_terms.txt default for search_blocked_terms.sh

Currently, search_blocked_terms.sh reads words from the local
unblocked_terms.txt, in which words may have been accidentally removed.

This change makes search_blocked_terms.sh read words from the global
blocked_terms.txt by default.

BUG=b:165908442
TEST=Run search_blocked_terms.sh with/without argument.
