Patch m4 lib for zetasql to the 1.4.19

[BON4]

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.
