Followup for CL 168297, a fix was released for the kernel bug https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236737

https://svnweb.freebsd.org/base?view=revision&revision=345741
https://svnweb.freebsd.org/base?view=revision&revision=346019
https://svnweb.freebsd.org/base?view=revision&revision=346020

Thus the bug won't affect 11.3-RELEASE and 12.1-RELEASE when they are out.

Update adjustFreeBSD32 to handle only FreeBSD 12.0-RELEASE ranges of freebsdVersion.

Updates golang/go#30899
