Moved $FreeBSD$ to its usual place after the CSRG id.

Fixed some style bugs for cam (superflous umask and missing newline).

Fixed bogons for apm. The pattern "apm*" matched too many things; apm
and apmctl were both made twice by `MAKEDEV all'. Hopefully no one
depends on MAKEDEV apm0' making apm or on MAKEDEV apm' making apmctl.
