My xulrunner-sdk-33 subfolder also does not have a 'b2g' subfolder. Nor does the 'obj-x86_64-unknown-linux-gnu' subfolder under my b2g32_v2_0 hg tree.

Doing this in xulrunner-sdk:

# ln -s bin b2g

...lets the mochitest runner progress to here:

So here's what does work (thanks to a tip from bug 1066042):

# hg clone http://hg.mozilla.org/releases/mozilla-b2g32_v2_0/ $MC/b2g32_v2_0
# cd b2g30_v2_0
# ./mach build
# cd obj-x86_64-unknown-linux-gnu/dist
# ln -s bin b2g
# cd $B2G
# export XULRUNNER_DIRECTORY=$MC/b2g32_v2_0/obj-x86_64-unknown-linux-gnu/dist
# ./mach mochitest-remote $PATH_TO_TEST_SCRIPT

The code that finds the --xre-path lives here:
https://github.com/mozilla-b2g/B2G/blob/master/tools/mach_b2g_bootstrap.py#L101

It used to be the case that it returned those xulrunner-sdk dirs, but ever since bug 1002545 it was changed to download the files from a recent b2g_desktop build instead. On trunk, it should find a dir in '$B2G/gaia/b2g_sdk'. I think what's happening here is that you're building on an older branch and are running into bug 1002545 (no ssltunnel). I just tested on trunk and things work.

You could probably simplify your workaround by just setting XULRUNNER_DIRECTORY=$B2G/gaia/b2g_sdk/<ver>/b2g and USE_LOCAL_XULRUNNER=1 in your .userconfig. I don't think there's any easy fixes here without backporting a whole bunch of stuff. I'd propose WONTFIX'ing and just sticking to the workaround for now, but I'll leave that up to you.
