[compiler-rt] [sanitizer_common][test-only] Specify full path for sort executable in popen.cpp (PR #171622)

[Dan Blackwell via llvm-commits]

https://github.com/DanBlackwell created https://github.com/llvm/llvm-project/pull/171622

This test has begun failing on iossim with 'sh: sort: command not found' in the stderr. I believe this may be due to the change to the lit internal shell not having 'sort' in it's path.

This patch adds the full path /usr/bin/sort to work around this.
