This commit changes the sysprop for overriding the branch bwc builds use
to be branch specific. There are 3 different bwc branches built, but all
of them currently read the exact same sysprop. For example, with this change
and current branches, you can now specify eg
-Dtests.bwc.refspec.6.x=my_6x
and it will build only next-minor-snapshot with that branch, while
next-bugfix-snapshot will continue to use 5.6.
