[compiler-rt] [compiler-rt][Profile] Temporarily Disable Test on AIX (PR #166637)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/166637

This was very hackily patched in
16ef893e9fdec2b08dafc82f5450b41834e09039 to not use env -u. The internal
shell does not support unset, but does supprt env -u. Disable the test
for now so we can enable the internal shell with a TODO to enable it
after the internal shell landing has stuck.
