Update devel/b2 to 0.7.2.

[gordon]

Robak,

Can you take a look at this update? It requires a new port I'm submitting (devel/py-logfury) which can be found as https://reviews.freebsd.org/D12135. Please take a look. I'm also willing to take over maintenance of the port if you aren't interested in it anymore.

Best,
Gordon

Put this after USES.

There has not been a 2.6 for 3.5 years, 2.7+ here would probably be clearer.

Move this before USES, and replace += with =.
