Any thoughts on how to fix this?

The bot doesn't have the tools installed, which is now being caught as it should be!

Infra: can we get the Xcode tools installed on these bots:

vm175-m1 (https://ci.chromium.org/buildbot/chromium.perf/Mac%20Builder%20Perf/4296)
vm168-m1 (https://ci.chromium.org/buildbot/chromium.perf/Mac%20Builder%20Perf/4294)
vm158-m1 (https://ci.chromium.org/buildbot/chromium.perf/Mac%20Builder%20Perf/4292)

vm669-m1 (https://ci.chromium.org/buildbot/chromium.chrome/Google%20Chrome%20Mac/32414)

This has been broken for a while, as they had the Command Line Tools installed, but otool moved out of path as not to break hermetic Xcode, which has since been removed from bootstrapping scripts back in Feb.

otool is now properly in path on the bots listed in #2. Long-term, probably best to pull in heremetic Xcode.
