games/scummvm: Update to 2.2.0

• Introduce A52 and CURL options to avoid possible QA stage errors with build environments that have already audio/liba52 or ftp/curl installed because the configure script automatically adds them as an additional dependencies in that case. [1]
  
  Set the A52 option as default as it improves the user experience with the "zvision" engine regarding audio/video playback.
  
  Leave the CURL option as non-default for now, because the ScummVM cloud storage is a fairly new feature that has been introduced since the 2.1.0 release. That option can be set as default later if there's great demand.

• Remove now obsolete patches which were required for newer versions of FluidSynth.

• Rebase the patch and post-processing of the configure script, switch to the new preferred location of man pages (since r523104) and avoid hardcoded occurences of ${LOCALBASE}.

• Many thanks to lme@ who maintained the port for over 13 years and offered me to take over maintainership.
