usb_drv: Add missing definition of __aligned macro

This macro is implicitly pulled in by libc-setjmp (via the libc's
cdefs.h). However, apparently not all sources include <setjmp.h>.
Unfortunately, for sources that do, this change produces a
double-definition warning. We should fix it by removing the dependency
from the libc's setjmp.
