@protobuf: fix build with pkgsrc gcc-10

Removing #define _POSIX_C_SOURCE 202405L is sufficient to fix the build
with pkgsrc gcc10.

This is for this bit of code:
int robust_close(int fd) {
#if defined(POSIX_CLOSE_RESTART)
  return posix_close(fd, 0);
#else
  return close(fd);
#endif
}

On most operating systems, posix_close doesn't exist anyway, so this code
is all irrelevant:

@$NetBSD$

Defining _POSIX_C_SOURCE breaks the build with pkgsrc gcc10.
It is only used to bring in posix_close which is not available
on most platforms, so make Linux-only:
