Not support alpine linux

[huan]

I'm switching my base image from node to alpine for my nodejs project wechaty: wechaty/wechaty#66

after npm install chromedriver in alpine Linux, it can not be run:

bash-4.3# ./node_modules/chromedriver/chromedriver/chromedriver 
bash: ./node_modules/chromedriver/chromedriver/chromedriver: No such file or directory

bash-4.3# ./node_modules/.bin/chromedriver 
events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: spawn /wechaty/node_modules/chromedriver/lib/chromedriver/chromedriver ENOENT
    at exports._errnoException (util.js:953:11)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:182:32)
    at onErrorNT (internal/child_process.js:348:16)
    at _combinedTickCallback (internal/process/next_tick.js:74:11)

    at Function.Module.runMain (module.js:577:11)
    at startup (node.js:160:18)
    at node.js:449:3

instead, we can get the right chromedriver by using apk add chromedriver for Alpine Linux

if we use file to show the two version, it seems the reason is that the npm version use libc & and Alpine Linux use musl.

bash-4.3# file /usr/lib/chromium/chromedriver 
/usr/lib/chromium/chromedriver: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-musl-x86_64.so.1, stripped

bash-4.3# file node_modules/chromedriver/chromedriver/chromedriver
node_modules/chromedriver/chromedriver/chromedriver: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.26, BuildID[sha1]=642a90ebc607bac377950226280b021e68fc8e9c, stripped

hope this could be fixed.

This package is wrapping the versions available on the original distribution, such as http://chromedriver.storage.googleapis.com/index.html?path=2.25/
Wouldn't apk add chromedriver demand root access? I don't think it is a good idea that this package demands that.
If you can get a mirror to host the binary, you can use the npm option on install, such as npm install chromedriver --chromedriver_cdnurl=http://npm.taobao.org/mirrors/chromedriver, or use the environment variable CHROMEDRIVER_CDNURL. See the readme for more info.
I don't think we can do more to support. If you see a way to evolve using the current code, let me know. I am closing the issue for now, but we can open it later if we find a way forward.
