Patch to increase out-of-memory score for localapps

The following should make the OOM-killer prefer to kill localapps on out
of memory conditions, instead of e.g. killing the ssh connection (which
would result in all localapps dying anyway).

I'm not using localapps so I can't test it, I was just reading the
"proc" man page and I came across it, so I thought I'd post it in case
anyone is interested in testing/committing it.

Cheers,
Alkis
