tests: add support for negative match patterns to match_grep
For the cases when we want that some patterns do not appear in the
output.
* tests/init.sh (match_grep): Add res and negated local variables; set
negated to 1 if pattern starts with "!", otherwise to 0; fail if negated
pattern has been matched.
