Work around build errors on MacOS 13.3 and XCode 14.3

After upgrading MacOS to 13.3.1 and XCode to 14.3 the gerrit build fails
with the following errors apparently caused by zlib:

$ bazelisk build release
...
external/remote_java_tools/java_tools/zlib/gzwrite.c:89:20: error: call
to undeclared function 'write'; ISO C99 and later do not support
implicit function declarations [-Wimplicit-function-declaration]
            writ = write(state->fd, strm->next_in, put);
                    ^

you mean 'fwrite'?

    if (close(state->fd) == -1)
        ^

To fix this follow the advise in [1] and set C standard to C90 globally.
Setting this only for zlib sources as recommended in [1] seems not to
work for the bazel version we are using.
