tests: convert the 'file://\$TESTTMP' rule to an automatic substitution

A script to generate nasty diff worst-case scenarios:
$ cat > s.py <<EOF
> import random
> for x in xrange(100000):
> print
> if random.randint(0, 100) >= 50:
> x += 1
> print(hex(x))
> EOF
$ hg init a
$ cd a
Check in a big file:
$ $PYTHON ../s.py > a
$ hg ci -qAm0
Modify it:
$ $PYTHON ../s.py > a
Time a check-in, should never take more than 10 seconds user time:
$ hg ci --time -m1
time: real .* secs .user [0-9][.].* sys .* (re)
