This patch disables the `noasan-strcmp.test` for AArch64 Linux as it
consistently fails on the buildbot machine while passing on other
AArch64 Linux systems.
We have seen similar issues on noasan-strncmp.test in past which had
random failures on certain machines/environments.
Following buildbot is failing in both check stage1 and stage2:
