makepkg: add new checksum algorithm via coreutils b2sum

coreutils 8.26 in December 2016 added this new hashing method which is
compatible with the existing md5sum and sha*sum tool usage, while using
the blake2 hash algorithm.

makepkg uses coreutils to provide source file integrity checks via
${integ}sum binaries and it makes sense to offer this as an additional
option.
