gcc-6.3.inc: Use ucontext_t not struct ucontext.

Use ucontext_t not struct ucontext in linux-unwind.h files.

Current glibc no longer gives the ucontext_t type the tag struct
ucontext, to conform with POSIX namespace rules.  This requires
various linux-unwind.h files in libgcc, that were previously using
struct ucontext, to be fixed to use ucontext_t instead.  This is
similar to the removal of the struct siginfo tag from siginfo_t some
years ago.
