bootid-logger: Add tests and refactor code (reland)

This CL adds tests for bootid-logger, and refactors the code for it.

The original CL had landed (crrev.com/c/2566323) but was reverted
(crrev.com/c/2596476) due to crash. This is reland of the original CL.

Added tests:
- Test to write an entry
- Test to write multiple entries to ensure the truncation
- Test to write multiple entries to omit the duplication
- Test to write boot-entry with boot id retrieved from /proc

Refactoring:
- Split the main logic to syslogcat.cc
- Improves nits mentioned in the comments in crrev.com/c/2428654
