[compiler-rt] [Sanitizer] Fix android test env issue (PR #142235)

[Ellis Hoag via llvm-commits]

https://github.com/ellishg created https://github.com/llvm/llvm-project/pull/142235

I attempted to fix android tests in https://github.com/llvm/llvm-project/pull/142207 (broken by https://github.com/llvm/llvm-project/pull/141820). They are still failing but now I have more info.

https://lab.llvm.org/buildbot/#/builders/186/builds/9504/steps/16/logs/stdio

ERROR: Can't open file: //foo.8862 (reason: 30)

I believe the reason is that on android the HOME and TMPDIR environment variables are not being set correctly, or they are not read correctly. (https://github.com/llvm/llvm-project/pull/142234#issuecomment-2923694428)

Also remove an extra %env left in a related test.
