[buildtools] Remove non-arch-specific mac clang-format

In preparation for using clang-format binaries built in clang rolls
which will result in per-arch clang-format executables
https://crrev.com/c/3533408 added the corresponding mac per-arch sha1
files. This change deletes the old mac clang-format.sha1.

If your project DEPS uses this mac clang-format.sha1, follow
and use the mac x64/arm64 clang-format sha1 files.
