MFC r361397, r361655, r361683: certctl(8) unprivileged & HISTORY correction
r361397:
Add an unprivileged mode where calls to install are passed appropriate
flags. For ease of integration, use the same flags as install:
-U unprivileged mode
-D <destdir> Specify DESTDIR (overrides the environment)
-M <metalog> Full path to METALOG file
r361655:
certctl.8: Correct the HISTORY section.
certctl was merged to stable/12 after 12.1 was branched.
r361683:
certctl: fix test syntax
test doesn't understand &&, but it does understand -a.
