Test: repo upload
Change-Id: I516200c81f31a2b3891a229277ac1cd15e5738a9
The rustfmt configuration is linked to the default from
build/soong/scripts. This is similar to how clang-format is setup for
system/core.
Test: Added a commit with a bogus lib.rs and run repo upload.
An error is returned by the rusfmt hook.
