[libc++][Android] Disable pbump2gig for Android

[rprichard]

Summary

Android devices frequently don't have enough memory to run this test.

e.g. On the API 33 x86-64 emulator with 2GiB RAM, the test triggers the
OOM Killer, the device reboots, and then adb shell exits with status
0 and no output.

I see the AIX CI fail. I assume it's unrelated, can you re-upload your patch to verify.
LGTM from libc++'s perspective, but please wait for @danalbert's approval and a green CI.

[rprichard]

No change.

LGTM, but note that rprichard is going to be a better POC for Android libc++ in the future :)

[rprichard]

Bump BuildKite again.

Thanks for the information.
