fix(plugins): state accumulation uses = instead of += (#1070)

Both wildfly-memory-usage and starface-java-memory-usage built up their
overall plugin state via `state += lib.base.get_worst(...)`. That adds
the state integers together: STATE_WARN + STATE_WARN = 2 which reads
as STATE_CRIT, STATE_WARN + STATE_CRIT = 3 which is outside the valid
STATE range entirely.

- wildfly-memory-usage: both the heap and non-heap branches combine
  three states (overall, used, committed). With the new variadic
  `lib.base.get_worst()` this is now a single clean call.
- starface-java-memory-usage: the heap and non-heap branches each
  combine two states (accumulated, used). Standard
  `state = lib.base.get_worst(state, used_state)` call.

Needs lib.base.get_worst variadic extension (shipped separately in lib).
