Sorry, a lot of these comments are irrelevant to the actual patch, but I
couldn't help pointing them out...

I was going to suggest that we simply make this:

  printf '%s\n' "${PACKAGER:-Unknown Packager}"

But then it occurred to me that if we just set this default value up
front, we don't need to treat this var as special...

Actually relevant to this patch, why not define this as
'write_kv_packager' to match other functions here, like
'write_kv_pkgname' and 'write_kv_pkgver'?

Wouldn't it be nice if we just *always* wrote the pkgbase?

Since 8a02abcf19, disallow pkgver overrides in package functions.
Therefore, I'm unclear on when we'd ever emit this basever attr.
