exit false should result in exit_status 1

[grosser]

When using Aruba::Processes::InProcess FakeKernel#exit does not translate false to 1, which results in Then(/^the exit status should( not)? be (\d+)$/) from lib/aruba/cucumber/command.rb to fail with has exit status of "1", but has "false"

ruby -e 'exit false'
echo $?
1

so FakeKernel needs a fix ... I can do the PR if that sounds right.

That does sound right to me. A Ruby behavioural compatibility improvement to FakeKernel.
