[PATCH v12 2/4] perf version: update --build-options to use 'supported_features' array

[Aditya Gupta <adityag@linux.ibm.com>]

Now that the feature list has been duplicated in a global
'supported_features' array, use that array instead of manually checking
status of built-in features.

This helps in being consistent with commands such as 'perf check feature',
so commands can use the same array, and any new feature can be added at
one place, in the 'supported_features' array
