sys/openbsd: sanitize setrlimit(RLIMIT_DATA) syscalls (#1231)
OpenBSD performs a strict validation of the RLIMIT_DATA soft limit
during memory allocation. Lowering the same limit could cause
syz-executor to run out of memory quickly. Therefore make sure to not go
lower than the default soft limit for the staff group.
This is one of the root causes of the high amount of reported "lost
connection to test machine".
