Title: Fix exit status on LoadError

Currently if a spec triggers a LoadError by calling `require` with a
nonexistent file, RSpec will exit with status 0 instead of 1. This can
allow entire spec suites to be skipped without notice in a CI
environment.

This patch rescues such errors and correctly exits with status 1.
