core2md: write error message with perror
The current failure message omits the underlying errno. This can
make diagnosing failures a bit difficult unless you run everything
through strace. For example:
$ core2md core /proc/self md
$ core2md core /proc/self md
Unable to generate minidump
Now we get the errno details:
Unable to generate minidump: File exists
