Attaching extra program to same functions system wide for api
and link tests.
This way we can test the pid filter works properly when there's
extra system wide consumer on the same uprobe that will trigger
the original uprobe handler.
We expect to have the same counts as before.

Running api and link tests also with pid filter and checking
the probe gets executed only for specific pid.
Spawning extra process to trigger attached uprobes and checking
we get correct counts from executed programs.
