create_subprocess doesn't work with PathLike objects

[JelleZijlstra]

• uvloop version: 0.8.0
• Python version: 3.6.1
• Platform: Ubuntu
• Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: Yes

The following test script fails as follows:

import asyncio
from pathlib import Path
import uvloop

async def make_process():
    await asyncio.subprocess.create_subprocess_exec('ls', cwd=Path('/tmp'))

asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
asyncio.get_event_loop().run_until_complete(make_process())

  File "uvloop/loop.pyx", line 2164, in __subprocess_run (uvloop/loop.c:39415)
  File "uvloop/handles/process.pyx", line 549, in uvloop.loop.UVProcessTransport.new (uvloop/loop.c:93764)
  File "uvloop/handles/process.pyx", line 49, in uvloop.loop.UVProcess._init (uvloop/loop.c:84744)
  File "uvloop/handles/process.pyx", line 38, in uvloop.loop.UVProcess._init (uvloop/loop.c:84464)
  File "uvloop/handles/process.pyx", line 233, in uvloop.loop.UVProcess._init_options (uvloop/loop.c:87896)
ValueError: cwd must be a str or bytes object

This works fine with vanilla asyncio. Fixing the bug is probably just a matter of calling os.fspath/PyOS_FSPath somewhere.

Fixed in master. Will be in the next uvloop release (0.9.0) soon.
