[Sanitizer] Fix android test env issue (llvm#142235)

I attempted to fix android tests in
llvm#142207 (broken by
llvm#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.
