py3: add a bytes version of os.name

os.name returns unicodes on py3. Most of our checks are like
    os.name == 'nt'

Because of the transformer, on the right hand side we have b'nt'. The
condition will never satisfy even if os.name returns 'nt' as that will be an
unicode.
We either need to encode every occurence of os.name or have a
new variable which is much cleaner. Now we have pycompat.osname.
There are around 53 occurences of os.name in the codebase which needs to
be replaced by pycompat.osname to support Python 3.
