George Hartzell f24398cde6 Add package for libbsd, add variant to expat for libbsd (#4945)
* Add package for libbsd, add variant to expat for libbsd

The recent expat release requires a high quality source of randomness.

CentOS 7 does not seem to have one, but one is available in libbsd.

This commit adds a package for libbsd and adds a variant to expat to
use it (defaults to False).

* Make libbsd default for newer, conflict for older

Make the libbsd variant default to true.

Conflict if you're asking for libbsd and an older version of expat.

This means that in order to install an older version of expat you'll
need to specify `~libbsd`.

* Rework so that 2.2.0 and 2.2.2 work by default

Get rid of the conflicts and use better constraints/tests in the
`depends_on` and the `configure_args` bits.
