As indicated via email, araujo@ is no longer interested in mainintaing the
sysutils/uefi-edk2-bhyve port. So take over maintenance, update it to be
the same as sysutils/uefi-edk2-bhyve-devel
and delete the latter port.
Fix a couple of issues portlint flagged about the version number and the last two lines of Makefile.
