Properly expose more constants on FreeBSD

The freebsd12 and freebsd13 modules should only be used for symbols that
_change_ in those versions, not for newly added symbols.  Mostly they
should be used for versioned ELF symbols.  It does no harm to publish
ordinary constants in the base FreeBSD module even if they weren't
defined in the lowest supported version of FreeBSD, but it does make it
much easier for consumers to use them.
