ci: point to FreeBSD headers

[kevans91]

This will hopefully allow the FreeBSD libusb build to locate the proper headers to build against now that freebsd_glue is installed.

(I suspect not merging yet is a good idea, since I can't trigger a Travis build against my branch)

I'm not sure how freebsd-glue is supposed to work -- most Linux distros don't ship with a sys/cdefs.h, as far as I'm aware, so there is no other sys/cdefs.h in this environment to #include_next.

It's working for me, except it's looking for dev/usb/usb.h which doesn't exist:

Ah, I missed that one... we'd need to clone the source tree for that and .include() in ^/sys
