[security] fetch(1) does not perform certificate verification

[blee]

fetch(1) on FreeBSD does not perform certificate verification, making it vulnerable to attacks such as man-in-the-middle.

confman should use something else, like wget.

This affects users running confsync over https.

(In [407]) Making confman use wget regardless of OS to allow support for certificate
verification on HTTPS URLs.

Leaving ticket open until merged into 1.9 branch.

See #49
