Ok, here is a minimum patch to do that.

Subject: t9119: do not compare "Text Last Updated" line from "svn info"

On the "Text Last Updated" line, "git svn info <file>" does not give the
timestamp of the commit that touched the path most recently, unlike "svn
info <file>".  Do not expect the output from two commands to match on
these lines.

There was a "ptouch" attempt to transplant the timestamp from svn working
tree files to corresponding git working tree files, which mostly hid this
difference, but is made pointless now with this change.  Remove the helper
function and calls to it.
