libmakepkg: look for architecture-specific hashes in get_integlist

`makepkg -g` looks for existing checksums in the PKGBUILD file, so that
it can generate new sums of the same type. Previously it only checked
variables of the form "sha256sums", and not "sha256sums_x86_64". That
meant it would always fall back to MD5 for packages with only
architecture-specific sources. This change makes it look at
architecture-specific checksums too to determine the type.
