py3: add os.getcwdb() to have bytes path

Following the behaviour of Python 3, os.getcwd() return unicodes. We need
bytes version as path variables are bytes in UNIX. Python 3 has os.getcwdb()
which returns current working directory in bytes.

Like rest of the things there in pycompat, like osname, ossep, we need to
rewrite every instance of os.getcwd to pycompat.getcwd to make them work
correctly on Python 3.
