sysutils/vagrant: update to 1.7.2

[mmoll]

Summary

I have two positive reports about a slightly earlier patchset from two people. Unfortunantely the maintainer did not react to any of my mails, so I would commit this and the dependent differentials after obtaining clearance here.
Proposed commit message:

sysutils/vagrant: update to 1.7.2

- switch to USE_GITHUB
- cleanup RUN_DEPENDS

Approved by:	swills (mentor), mat (mentor), Joe Benden (maintainer, timeout)

Shouldn't this be 1.7?

Should set DISTVERSIONPREFIX instead.

use DISTVERSIONPREFIX

That should go, it's the default.

The gemspec says ">=1.5.3, <1.8.0" and does indeed not work with newer bundler versions (which was the reason why sysutils/bundler17 was created). However, I try to reflect the versions in the gemspec in ports Makefiles.

[swills]

Address mat's comment, then we can approve.

[mmoll]

should already be addressed within Diff 6487

[swills]

Ah, great, sorry, misread. Approved!
