The previous algorithm had the problem that if you had builds
A = browser+os.linux.x86_64
B = browser+os.osx.x86_64
available and came in looking for "something that satisfies 'browser'
and 'os.osx.x86_64'", Meteor would happily say:
"Neato-keen! 'A' satisfies 'browser'. And 'B' satisfies
'os.osx.x86_64'! Hey, that's all I needed! Let's download
both 'A' and 'B'! Hooray!"
when choosing just 'B' would have been good enough.
