bazel_roll: Better handle trimming around rules

The code for extracting the center of a match used to trim a bunch of
lines from the end, then recalculate the center and trim a bunch of
stuff from the beginning. If many lines were removed from the end, then
the updated center could be on a different rule and the parsing would
fail.
