speed up bsd.port.mk slightly

[Marc Espie <espie_(_at_)_schutzenberger_(_dot_)_liafa_(_dot_)_jussieu_(_dot_)_fr>]

bsd.port.mk can trim two external processes off.
- We are OpenBSD, this doesn't work anywhere else.
- OPSYS_VER is redundant with sys.mk.

Ok to install ?


Please note that the COMES_WITH test is potentially broken, and has always 
been so. This will break in two years, if we don't switch to 3.x before
that.
