[tor-commits] [ooni-probe/master] Update user agent strings for user agent randomization

[art@xxxxxxxxxxxxxx]

commit 66cbb71acfaf158fa8380a44395f83c95e6e7548
Author: Arturo Filastò <art@xxxxxxxxx>

    Update user agent strings for user agent randomization
    
    They are now taken from the PETS2010 paper "How unique is your browser" as the
    user agents with the largest anonymity set.
    Note: this is probably no longer true as of today, but I could not find a
    better source for mostly used user agent strings and it's for sure better than
    what we had before (We were considering highly used Opera 8.1).
