autotest: Refactor reap_spdk_processes()

Browse Source 
This is done in order to speed up entire lookup and be more robust
with matching target processes. This implementation also tries to
detect processes executed outside of the local repo workspace - this
is most relevant for the CI where lingering processes may come from
different jenkins workspaces (i.e. executed by different jobs).
