IMPROVEMENT security/libb2

Upstream of libb2 started offering distfiles via githubs release
infrastructure.

Changes to the port:

- Move from GH_* to MASTER_SITES and DISTNAME
* Set EPOCH as version numbering has changed
* Set HOMEPAGE
- No need to pull in automake and libtool
* Drop BDEPs
* Change CONFIGURE_STYLE
- Follow Makefile.template
- Change email address MAINTAINER

'make test' runs successfully, build tested all customers, and run
tested with borgbackup.
