[compiler-rt] UBSan: Disable 3 of the new alignment assumption tests on android.

Once again, just like with r338296, these tests seem to only have
failed sanitizer-x86_64-linux-android, so let's just disable them,
since that seems like the pre-established practice here..

To be noted, they failed on some configs there, but not all,
so it is not XFAIL.
