Avoid false alarms from git secrets in hiddenapi flags csv files.

They can contain lines like:

  Lfoo/bar/Something$Mumble;->KEY:Lfoo/bar/Something$Mumble;

where "KEY" gets picked up by a "git secret --list" regexp.

Test: prebuilts/runtime/mainline/update.py --local-dist ../aosp/out/dist
  with freshly built prebuilts in ../aosp/out/dist
