Really enable core dumps in Linux
commit e1f1ce68e1f685400a8c68bcec14018e3d1fc29d
Author: Rusty Russell <rusty@rustcorp.com.au>

source3: dump core on Linux, even after seteuid/etc.
The "dumpable" flag is reset on every call to set*uid, so we need to
reset it to 1 in the signal handler itself.
This code dates back to commit ac01fda2b97b 6 years ago :(
