handle utf8 PWD

Summary:
- [python] decode strings coming from `os.*` commands
- [python] decode strings coming from the command-line
- [python] encode a few remaining unicodes into strings
- [java] replace lex/yacc parser for javac verbose output by regex-based matching to handle unicode in paths
- [make] random fix of `make test` to have `make clean test` work
- [integration tests] add e2e build integration tests for utf8 in the PWD

Closes #76
