Rollup merge of #109452 - jfgoog:ignore-vendor, r=ozkanonur

Ignore the vendor directory for tidy tests.

When running `x.py test` on a downloaded source distribution (e.g. https://static.rust-lang.org/dist/rustc-<version>-src.tar.gz), the crates in the vendor directory contain a number of executable files that cause the tidy test to fail with the following message:

tidy error: binary checked into source: <path>

I see 26 such errors with the 1.68.0 source distribution. A few of these are .rs source files with incorrect executable permission, but most are scripts that are correctly marked executable.
