Bump bindgen version

This bump was required as it was causing fix753 workaround to fail.

Hi Albert! This looks fine to me, but just for my curiosity can you explain what the new bindgen version does differently that makes things work?

Checking the changelog, I think the change that is probably making it work is this one: rust-lang/rust-bindgen#2779

From my experiments, it looked like MARK_FIX_753 macro was not being parsed correctly. The fix is for function-like macros, whereas the MARK_FIX_753 macro is a declaration. But it is the only related thing I've seen at first glance, so it is a fair guess.

Either that, or some of the dependencies that have been updated in the crate, for example, clang: rust-lang/rust-bindgen@39232cc

I'm not sure I get it because I never ran into any problem, but in any case this update should be harmless (and the extra rebuild condition is useful). Merged, thanks!
