tb@ pointed out that the recent update of borgbackup/2.0
(2.0.0b9->2.0.0b12) causes pkg tools to think the version went
backwards. Issue is caused by me thinking that 'b' is supported as
special version string. As a result from lexicographically sorting
2.0.0b9 is seen as newer than 2.0.0b12.

Solution has also been pointed out by tb@: Fix this by setting PKGNAME
to include the supported 'beta' string and setting EPOCH.

Tested by upgrading from 2.0.0b9 and 2.0.0b12.

OK?
