rc: Start testing the rc(8) framework (beginning with *_oomprotect)
This change adds 2 tests to make sure that the *_oomprotect variable sets the protection against OOM killer properly within rc(8) scripts. This is also adding the first tests for the rc(8) framework. More tests will be added as we go. PR: 256148 Approved by: des MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D35745
