logd: filters remove leading expire messages and rate

(cherry pick from commit 047cc0729fd837a03b99db901941c1421ef15f96)

- Cleanup resulting from experience and feedback
- When filtering inside logd, drop any leading expire messages, they
  are cluttering up leading edge of tombstones (which filter by pid)
- Increase and introduce EXPIRE_RATELIMIT from 1 to 10 seconds
- Increase EXPIRE_THRESHOLD from 4 to 10 count
- Improve the expire messages from:
   logd : uid=1000(system) too chatty comm=com.google.android.phone,
                                                   expire 2800 lines
  change tag to be more descriptive, and reduce accusatory tone to:
   chatty : uid=1000(system) com.google.android.phone expire 2800
                                                               lines
- if the UID name forms a prefix for comm name, then drop UID name
