unix: don't abort when getrlimit() fails
unix: don't abort when getrlimit() fails

It was reported that `getrlimit(RLIMIT_STACK)` fails on some aarch64
systems due to a glibc bug, where the getrlimit() system call wrapper
invokes the wrong system call.

Libuv could work around that by issuing a `prlimit(2)` system call
instead but since it can't assume that said system call is available
(it was added in Linux 2.6.36, libuv's baseline is 2.6.32) it seems
easier to just use the default 2M stack size when the call fails.
