Strip __RCSID() and __SCCSID() strings by default when building libc.

Browse Source 
This is in preparation for changes to update the various ID strings in
libc's source.  CSRG ID strings will use __SCCSID() and there are some
existing uses of __RCSID() for NetBSD ID strings already.  These are
generally under either an explicit #if 0 or an #ifdef LIBC_SCCS so are
off by default and this change preserves that existing behavior.
