Commit cbec75e2f3 updated `runDocker()` to load
plugin-stubs before `processAliases()` was executed. As a result, plugin
stubs were considered as "builtin commands", causing the alias verification
to fail;
Without alias installed:
```bash
docker version
Client:
Version: 22.06.0-beta.0-140-g3dad26ca2.m
API version: 1.42
Go version: go1.19.1
Git commit: 3dad26ca2
Built: Wed Sep 28 22:36:09 2022
OS/Arch: darwin/arm64
Context: default
...
```
After running `docker buildx install`;
```bash
./build/docker buildx install
cat ~/.docker/config.json
{
"aliases": {
"builder": "buildx"
}
}
./build/docker version
not allowed to alias with builtin "buildx" as target
```
This patch moves loading the stubs _after_ the call to `processAliases()`, so
that verification passes. As an extra precaution, the `processAliases()` function
is also updated to exclude plugin-stub commands.
Note that cbec75e2f3 also introduced a performance
regression, which may be related to the early loading of plugins (and creating
stubs); it looks like various other code locations may also be loading plugins,
for example `tryPluginRun()` calls `pluginmanager.PluginRunCommand()`, which
also traverses plugin directories.
We should look under what circumstances the plugin stub-commands are actually
needed, and make sure that they're only created in those situations.
