[3p][rust][bazel] Remove unnecessary license metadata

build/bazel/update-rustc-third-party/BUILD.bazel was caught in an LSC
that adds default licenses to all BUILD.bazel files, but it actually
doesn't need one, so removing it. Including it actually fails the build
because we don't provide a license target in the workspace crate-vendor
is run.

I reran `fx update-rustc-third-party` to confirm this fix, which also
removed default license from two generated BUILD.bazel files.
