Chris Bracken 970d2e9081 Roll buildroot to c37164f39300c6e42560a5853e16a919688f7b86 (flutter/engine#27967)
This eliminates the landmines hook.

build/landmines.py writes out a .landmines file at the root of the
buildroot. The first step of a `gclient sync` is to check for diffs
between that file and the new one, and if found, a clobber is performed.

We never actually use this functionality, and the code calls rmtree()
which (at least on macos) appears to choke on symlinks.

This deletes these scripts, and will be paired with the deletion of the
first gclient hook in the DEPS file in flutter/engine during the roll.

If we ever need this functionality, it's relatively straightforward to
add it back.

Issue: flutter/flutter#87960
