tests: Fix race condition in profile locking test.
Previously, there was a possibility that "guix install emacs" would grab the lock before "guix package -m $module_dir/manifest.scm". When that happened, the test would start building Emacs and all its dependencies, which could take a while and some disk space. This is a followup to b1fb663404894268b5ee92c040f12c52c0bee425. * tests/guix-package.sh: In profile locking test, emit "$module_dir/ready" from the manifest and wait for it to exist before running "guix install emacs".
