LOG: [compiler-rt][asan] Disable two tests on Arm Thumb

I can't be sure of the cause but I believe these fail
due to to fast unwinding not working on Thumb.

Whatever the case, they have been failing on our bots
for a long time:
https://lab.llvm.org/buildbot/#/builders/170/builds/46

Require fast-unwinder-works for both.
