Patch m4 lib for zetasql to the 1.4.19

### Description

The current version of `m4` (v1.4.17) is not compatible with the `ubuntu:22.04` base Docker image. When Bazel attempts to build `ml_metadata_store_server`, it fails with the following error:
```
/root/.cache/bazel/_bazel_root/2b5e54baa61e12f7face76121c87337a/sandbox/processwrapper-sandbox/1/execroot/ml_metadata/external/m4/lib/c-stack.c:55:26: error: missing binary operator before token "("
55 | #elif HAVE_LIBSIGSEGV && SIGSTKSZ < 16384
| ^~~~~~~~
```
The issue appears to stem from Bazel using `m4` version **1.4.17** for `zetasql`, which is incompatible with `ubuntu:22.04`. A newer version of `m4` (v1.4.19) patch for `zetasql` may resolve this issue.
