the ustat interceptor has been added in 2013, probably as part of the work on msan.

[sanitizer] A bunch of linux system call handlers.

I bet some code uses ustat and was causing msan false positives. 
We don't seem to have tests for it, and such a test doesn't appear trivial for the LLVM test suite.

What will happen on pre 2.28 if we remove this interceptor? 
Will msan get new false positives?
