Correct the "newbus" FreeBSD_version entry. (FreeBSD_version actually
was not bumped after the newbus import. :-( [shame on them].
So I moved it to the ceiling of the closest value. What was claimed to be
the FreeBSD_version for "newbus" is really for "deregister_frame_info
dynamic linker bug fix" and EGCS import.

Add 3.3 and 3.2 RELEASE's __FreeBSD_version values.
