Andreas Kling eeb4f2fa9b Kernel: Exclude userspace heap memory from coredumps by default ...

When a process with a large heap crashes (e.g WebContent), it gets very
cumbersome to dump out a huge amount of memory.

In the vast majority of cases, we're only interested in generating a
nice backtrace from the coredump, so let's have the kernel skip over
userspace heap regions when dumping memory for now.

This is not ideal, and almost a little bit ugly, but it does make
investigating 500 MiB WebContent crashes significantly easier for now.
