Since cgit now returns a 404 error when the snapshot filename cannot be
resolved to a commit object, the testscript needs to request a valid
snapshot name.
Also, the script assumed that the toplevel directory in the snapshot
would get the name of the repository but it's now named similar to
the requested snapshot.

The struct member was introduces in git commit d53fe8187c38, but the cgit
testsuite failed to detect that cgit always generated archives without
prefixes, i.e. the result from cgit_repobasename was ignored.
This fixes the bug and the testsuite.
