Bazel: Use hyphen instead of underscore in external repository names

Recent Bazel versions support the hyphen character in external
repository names. On the Gerrit project, the repository names
were harmonized to consistently use hyphen.

As a side effect, it is no longer possible to build jgit from source
in the gerrit tree, due to the different repository names.

Rename the dependencies to use hyphens, consistent with gerrit.
