Updated bindgen version.

[azriel91]

Just some maintenance -- trying to bump dependencies. I haven't got a Mac to test this on so would need someone to test this.

The code change is based on:

• The link options are ignored. rust-lang/rust-bindgen#104 (rust-lang/rust-bindgen@8e3e585)
• Flag for #[link = "..."] Attribute rust-lang/rust-bindgen#1358

Would like to update coreaudio-rs as well after this

Thanks a lot @azriel91!

Unfortunately I don't have a mac to test this on either atm - might leave this open until a kind soul with a mac drops by and gives this a test :)

IIRC @reuben has had a problem with a too old bindgen version. Maybe they'd be available to test it?

i tested this per @azriel91's instructions

1. clone coreaudio-rs
2. point coreaudio-rs at this branch of coreaudio-sys
   • Compiling coreaudio-sys v0.2.2 (https://github.com/azriel91/coreaudio-sys.git?branch=maintenance/bump-bindgen-version#129d9577)
3. run cargo run --example sine in coreaudio-rs

it worked fine (made a tone audibly) on OSX Yosemite 10.10.5 with stable rustc 1.29.2 (17a9dc751 2018-10-05) and nightly rustc 1.31.0-nightly (e7f5d4805 2018-10-18)

Works on 10.13.5 for me with both stable and nightly.
