plugins: make 'plugin startdir' 's runtime path independant

Browse Source 
This does the same as for the 'start' subcommand for the 'startdir'
one.

Note that we could fail to start the last plugin of a directory, but
have succesfully started the precedent plugins. This will make us return
an error to the user while some of the plugins have been started, but we
still don't end up in a transient state with
half-configured-half-errored plugins.
