devel/aws-sdk-cpp: make PulseAudio dependency optional

[olgeni]

Summary

• Add PULSEAUDIO option (enabled by default) for text-to-speech audio output
• Move libpulse.so dependency from mandatory to optional based on PULSEAUDIO option
• Add patch to respect FORCE_NO_PULSE CMake flag to disable PulseAudio detection
• Allows building without audio dependencies when text-to-speech audio output is not needed

I made this because I have server builds on poudriere with no pulseaudio and noticed it sneaking in :)
