registry: drop yosys-0.64 fork registry, BCR #8862 landed

yosys 0.64 (and abc 0.64-yosyshq.bcr.1) are now published on
bcr.bazel.build, so the oharboe/bazel-central-registry fallback added
while bazelbuild/bazel-central-registry#8862 was pending is obsolete.
Dropping the --registry lines entirely also removes the explicit
bcr.bazel.build entry: BCR is Bazel's default registry when no
--registry flag is set.

Verified with 'bazelisk mod deps' in the root, gallery, and
test/downstream workspaces.
