[compiler-rt] [Sanitizer] Use %device_rundir/ to fix test (PR #142274)

[Ellis Hoag via llvm-commits]

https://github.com/ellishg created https://github.com/llvm/llvm-project/pull/142274

I attempted to fix this test in https://github.com/llvm/llvm-project/pull/142235 but we a new error.

https://lab.llvm.org/buildbot/#/builders/186/builds/9524/steps/26/logs/stdio
> ERROR: Can't create directory: /var

The path we want is actually at `/data/local/tmp/Output/var/...`.

I found `%device_rundir/` evaluates to this prefix on android, and nothing otherwise.
