Checksums arrays should be filled with values provided by upstream. We
currently have md5 set as an unsecure default, and are constantly asked to
change it to sha2. However, just changing the default to a stronger checksum
gives the user the impression that "makepkg -g" checksums are perfect.
Instead, change the default checksum to a CRC, to make it clear that any
checksum generated purely by "makepkg -g" is not ideal.
