Kyle Evans 022b70f504 picobsd: add deprecation notices
Notices appear both in picobsd(8) (near the top for easy notice) and are
also printed to stderr on every invocation of picobsd for visibility.

The tentative date for removal is October 31st, as no volunteers have
stepped forward at all from postings to -arch@ at least.

No objection from:	-arch@
MFC after:	3 days
