MFC r335277:
sysrc(8): Exit with failure on API error
Fix exit status when f_sysrc_set() fails. Errors in the underlying API
provided by bsdconfig(8) -- /usr/share/bsdconfig/sysrc.subr -- were not
being communicated back to the command-line. This was affecting ansible
modules using sysrc as they were not able to accurately test for error.
