  regen/embed.pl:  Hide most KEY_foo symbols from XS

There are a lot of symbols in keywords.h that are visible to all XS
code.  Most code has no business knowing about these.

I've tried removing them all before, but that causes cpan failures.

Now, I have grepped metacpan for these, and only a few are actually
used.  They are
    'my', 'our', 'sigvar', 'KEY_UNITCHECK'

So I'm trying again, early in the development cycle, leaving just the
ones listed above
