base: Fix ucontext compilation error for macOS
ucontext functions (like getcontext, setcontext etc) have been marked as deprecated and are hence hidden in latest macOS releases. This patch uncovers them; warnings wil be produced but compilation won't fail since -Wno-error=deprecated-declarations flag is currently used.
